Modelling and the Behaviour of ICF Wall Structures

In that study, first, the behaviour of insulated concrete form walls with and without openings were analysed numerically by Abaqus and Sap2000 under different axial pressure levels. In screen grid insulated concrete form wall specimens, the lateral load capacity varied between 152kN to 362.6kN. The lateral load capacity of flat insulated concrete form walls varied between 160.17kN (in zero axial pressure) to 593.42KN (under an axial pressure which is equal to 35% of characteristic concrete strength). Later, a three-story structure was considered, to be constructed using screen-grid insulated concrete forms, flat insulated concrete forms, and conventional walls. According to the pushover analysis, it was seen that the structures showed nearly a linear elastic behaviour and the structures are rigid. By using screen grid insulated concrete form walls, it’s possible to have a lateral load capacity which is 56% of the capacity of structure with conventional walls. By using flat insulated concrete form walls the capacity increased to 69% of the capacity of structure with conventional walls. The ICF system can be considered as an alternative fast construction method if rigid structures are aimed to be designed.
