There are several widely used structural
softwares to analyze buildings under dynamic loads, but many of these programs
use arithmetic formulations to calculate the mass and stiffness matrices of
shear walls with only 8x8 elements that ignore the rotational mass and
stiffness values. Also, during the dynamic analysis, a system diagonal mass
matrix containing only elements in the x and y directions is used. The
previously mentioned calculation assumptions may lead to unrealistic structural
calculations besides these assumptions should be replaced by more realistic
calculation formulas and methods. In this paper, a two-part FEA computational
program was developed to provide actual structural dynamic analysis. The first
part of the program is called YAY2020-Static encoded by FORTRAN compiler and
the second one is called YAY-Dynamic encoded by MATLAB interpreter. In YAY2020
program, a special rectangular element formula with 12x12 elements and three
degrees of freedom at each element’s nodes is used to calculate shear wall mass
and stiffness matrices to obtain system full-size stiffness and mass matrices
that contain both diagonal and non-diagonal elements. Results obtained using
YAY2020 software will be compared with some structural analysis techniques such
as shear building and wide column, to study the feasibility of using these
techniques. All obtained results by YAY2020 will be compared with the commonly
use FEA structure software SAP2000.
