Özet

There are many widely used structural programs to calculate static loads' effect on buildings, meanwhile, a set of calculations’ assumptions are used as a basis of these programs. These assumptions may lead to unreal structural calculations and behaviors. One of the most important assumptions is the stiffness matrix of shear walls which is only composed of 8x8 elements ignoring the rotational stiffness values. In this study, a computational program based on the finite element method was developed using FORTRAN programming language to study the effect of static loads on planar structures. This program is called YAY2020. In the developed program, a special rectangular elements’ stiffness matrix formulation with 12x12 will be used to consider rotational deformations of the share wall elements. The correctness of this formulation has been proven by comparing it with Timoshenko beam analytical analysis. The aforementioned formulation was not in the literature until recently introduced by Öztorun. All results obtained by YAY2020 will be compared with the commonly used SAP2000 software.
