Abstract

 This paper deals with simplifying the modeling of complex walls with openings as separate columns and beams accompanied with correction factors so that the structural behavior of the 
complex walls with openings and the simplified models is almost the same. The wall rigidities of the original wall and the simplified modeling case are calculated by subjecting these walls to the same horizontal force and then calculating the horizontal displacement. 
A multiplication factor is introduced for the area of the columns of the simplified model to account for the difference in the horizontal displacement in order to have almost the same displacement in the prototype and the model. Finite element model was carried out on the original wall while beams and columns are adopted in the simplified structural models. This modeling is very important in designing multistorey buildings especially when the capacity of the computer is limited.
