ABSTRACT
Direction of joists arrangement in roofs is a major parameter which is by engineers through experience or through suspicion & opinion. This parameter directly affects the weight of building. We, therefore, decided to study a method to optimize the 3-D frames regarding to direction of joists. Don’t remember that not only this paper focuses on joists arrangement but also optimize the profiles of elements (beams, columns, wind brace). Following states may be study in optimization process of joists direction and profiles 3-D frame’s elements using GA regarding to capacities of prepared software: 1-static analysis 2-dynamic analysis 3-making the bending 3-D frame system 4-making the joint 3-D frame system as well as wind brace system 5-making the 3-D compound bending and joint frame system 6-ability to make any type of extensive & tie load 7-analysis and designing under any desired load.
