            <description><![CDATA[The present work brings together various intervention solutions on similar buildings in the city of Oradea, dating from the same period: around the 1900s. The buildings of the study are not historical monument buildings, but in the General Urban Plan of the city of Oradea, they are symbolized as buildings of historical value. The structural system of the buildings is similar, as well as their shape. The constructions had various initial functions and the interventions on them are carried out in order to change the use, also in order to bring them to the current exploitation and performance norms. Consequently, the work presents various ways of approaching these constructions from an architectural and structural point of view, giving solutions for their value recovery. Depending on the proposed function, the interventions are carried out respecting the architecture of the buildings as well as their valuable elements, which demonstrates a correct attitude of the actors involved for the transmission of valuable architectural and structural qualities to future generations. At the same time, the work proves that there are solutions in this sens e, putting the creativity of architects to the test. Through this type of intervention, the development of the city is supported in a balanced way by valuing and respecting the valuable elements of historical buildings.]]></description>

            <description><![CDATA[In this paper, the authors present research conducted through case studies on historical monument constructions situated on challenging foundation soils, where the foundation structure has also been affected. The constructions in question are historical monument buildings, typically over 100 years old. The destructive factors causing foundation degradation and affecting the soil’s resistance parameters are mainly leaks from water networks but also include certain intervention works carried out in the immediate vicinity of the monument. The resulting differential settlements motivated in-depth geotechnical studies as well as measures for soil stabilization and infrastructure reinforcement. The results of the research have supported the intervention works adopted by the authors, many of these case studies having also been executed to date. In this context, the article presents highly valuable material for specialists in adopting intervention measures for infrastructure reinforcement.]]></description>

            <description><![CDATA[Buildings are responsible for a significant portion of global energy use and greenhouse gas emissions. With population growth and urbanization on the rise, we have to rethink the way we build cities to enable greener and smarter living for all. Building with a vision for the future means thinking ahead to reduce our environmental impact. In this context the green certification of buildings is a method of evaluating their energy performance and environmental impact. This study examines environmental assessment tools commonly used for building green certification, including LEED (Leadership in Energy and Environmental Design), BREEAM (Building Research Establishment Environmental Assessment Method), and others used in Romania. These tools evaluate the sustainability of buildings across categories such as energy efficiency, water use, materials and resources, indoor environmental quality, and site selection. Choosing the right tool depends on the specific goals, location, and size of the building. Overall, these assessment tools provide a framework for promoting sustainable building practices.]]></description>

            <description><![CDATA[This paper analyses the influence of structural conformation on the behaviour of mixed structures. Mixed structures made of load-bearing masonry and reinforced concrete frames are often found as a structural solution, both in Romania and abroad. The mixed structural system can be used for civil, industrial or agricultural constructions. Such a structural solution is frequently reached due to the need to have larger free spaces from an architectural point of view. In principle, mixed structures combine the advantages of load-bearing masonry structures and the advantages of frame structures, but in the design of these structures, great attention must be paid to the conformation of the structure and especially in the areas of interaction between the load-bearing masonry and the frame structure.]]></description>

            <description><![CDATA[Loessoid soils are a special category amongst the continental sedimentary formations in the quaternary era. The term “loess” comes from the german word lose or los, used around the Rhine River region, and its meaning is loose, porous, crumbly. Loess has high porosity due to its macropores, which are visible to the naked eye and it is also very sensitive to humidity. This last characteristic has caused a lot of problems in the construction and operation process of buildings; it also made loessoid soils fit into the cathegory of very difficult terrains to build on.Punching settlement takes place when the foundation body pierces through the porous environment due to the breakage of its contracting macrostructure. This penetration effect leads to the creation of a plug of material that has reduced porosity, delimited by a contour that closes on the perimeter of the foundation surface.Punching settlement has been studied in the past by I. Chercasov in 1967, A. Chirică after 1990 and C. Ciurea after 1999.The purpose of this paper is to highlight the phenomenon of punching settlement through numerical modeling using the following calculation programs: COSMOS/M, which uses the finite element method in various linear and nonlinear, static and dynamic problems from various fields, and the FEM module in the GEO5 program, which is a modern calculation program specialized in solving geotechnical engineering problems.]]></description>

            <description><![CDATA[Maritime transport plays a crucial role in the global economy, facilitating international trade in goods and services. With the increasing volume of transported goods, large-tonnage ships have grown significantly in size, imposing substantial demands on berthing structures. This article examines the impacts of large-tonnage ships on quays and other berthing structures, highlighting the challenges and available solutions. Berthing structures are classified and analyzed based on the materials used and the type of structure, including gravity quays, sheet pile quays, and jetties.Large-tonnage ships are classified based on their carrying capacity and technical specifications, with each type of vessel having distinct operational requirements. The stresses on berthing structures include static pressure, impact during berthing, and bollard pull. The scour phenomenon, caused by the water jet generated by ship propellers, is a major concern as it can lead to the instability and degradation of quays.Traditional protection methods, such as the use of riprap and reinforced concrete, are complemented by modern solutions, including composite materials and advanced technologies like 3D printing. These innovations provide durable and adaptable solutions for quay protection.In conclusion, the design and implementation of effective protection measures are essential to ensure the durability of port infrastructure. Recommendations include the use of a combination of traditional and modern methods, continuous monitoring, and the adoption of sustainability policies. This enables ports to effectively address the challenges posed by large-tonnage ships while maintaining long-term safety and functionality.]]></description>

            <description><![CDATA[There is a global concern for reducing energy consumption and protecting the environment. The use of products with high thermal resistance, to make the envelope of a building, favours the reduction of energy consumption for heating/cooling of building and, implicitly, the reduction of CO2 emissions. The replacement, total or partial, of the basic components of the concrete compositions, can lead to the obtaining of innovative products with modified physical-mechanical properties, which meet the energy efficiency requirements of buildings. The study examines the effect of replacing the volume of sand in percentages of 10%, 20%, 30% and 100% with an equivalent volume of perlite, and the results have underlined that these compositions reduced density and thermal conductivity, compared to the reference concrete. The research carried out has emphasized that perlite can be successfully introduced in the production of concrete blocks used for non-load-bearing external wall panels, the outstanding feature being the reduced their thermal conductivity and weight. The paper identifies solutions for the use of perlite in the prefabricated construction industry.]]></description>

            <description><![CDATA[It is most likely that at the beginning of the 21st century, with the 4th industrial revolution, we will find ourselves at the borderline between technique and technology. The question underlying this article is whether the technological advance that the construction industry presents today can lead to the full replacement of the technique in the testing laboratories. Decisions on structural systems extracted from these laboratory-made physical models were often accurate, but the cost and time involved made the validation method low-yield. Today, through digitalization, all structural concepts can be directly realized in 3D with software specially designed for the AEC (Architecture, Engineering &amp; Construction) industry. Models made in this way can be developed down to the smallest detail, can be calculated and dimensioned from a structural point of view under different assumptions, and then can be georeferenced and managed from the point of view of assets.]]></description>

            <description><![CDATA[Large panel structures were used on a large scale between 1975-1987 for block structures, being one of the solutions with high productivity for that period. Considering the appreciable volume of residential buildings with such a structure, the author group proposed to conduct research on the behavior of these structures, both in seismic actions and in other actions as a whole doing research on the way of behavior over time. The results of this research led to the application of appropriate methods and techniques for their rehabilitation, for some intervention works as a result of some identified shortcomings. Mainly the buildings that have facades made of large panels were studied, but buildings that were made with such a structure in their integrity are also presented. The obtained results offer valuable material in the development of knowledge and in the assessment of the degree of risk and vulnerability.]]></description>

However, the findings also highlight the substantial challenges posed by legislative and economic instability. The analysis emphasizes the critical importance of stable and supportive fiscal policies for the sustainability of small and medium-sized enterprises (SMEs) in the construction sector. By analyzing financial data and industry statistics, the study identifies a clear correlation between legislative changes and the financial performance of SMEs, reinforcing the need for a consistent regulatory framework to foster sustainable growth and employment opportunities within the industry.]]></description>
