Abstract
The implementation of Computer-Aided-Software, coupled with matrix and finite element techniques permitted the analysis and design of structures to the desired degree of accuracy and modelling. The successfulness of micro-computers in a vastly business oriented market has prompted the structural engineer to take advantage of cheaper and efficient micro-computers in the analysis and design of structures particularly the high-rise buildings. The availability of a comprehensive, integrated software for the analysis and design of high-rise building frames that can be operated on a micro-computer is either not currently available in the market or the available software programs do not fulfill the needs of the present day structural engineer.
The study as a part of master's thesis is aimed at developing an integrated, interactive and reliable software for the analysis and design of high-rise building frames suitable to a micro-computer and to make it user-friendly. The program has two main subroutines - one for the analysis and the other one for design. The design routine has two basic options - one for the design of compression members and the second one for the design of beams. Another subroutine is included to find the equivalent static lateral loads due earthquake effect.
Five problems are considered for the analysis including three different types of shear walls. The design of some of the typical sections was carried out based on the bending moments and shear forces obtained from the analysis routine. The results of the ANALYSIS routine are compared with ANSYS CAD program available at the Institute and were found to be in excellent agreement with the program run on VAX-11/750 mini-computer. The efficiency of the ANALYSIS routine lies in pre-selecting the code number sequence and the use of Cholesky's decomposition for solving the banded stiffness matrix is very effective for medium sized problems.
