Abstract
The use of optimization process is a much-needed step in the field of construction today. But optimization is not being used very efficiently in structural engineering. Weight optimization is one of the structural optimization processes which optimizes the weight of the material used in the construction. The process provides an optimum area of cross-section for the steel sections. By optimizing the weight, the material cost has been reduced. It helps in improving the economic sustainability. The paper presents a study of optimization of trusses using genetic algorithm. The trusses considered for optimization are a two-bar truss, a three-bar truss and a ten-bar truss. The software used for this process is MATLAB2013a. The results are cross-checked using STAAD.Pro and manual calculations.
Description
Today, the world is developing at an unbelievable pace; the amount of resources it
has been providing is declining rapidly. The demand for resources is increasing with
the advances we are making in the present world. We have to make sure that the
resources are not overused; they need to be used efficiently. Keeping the economic
factor in mind, the excess use of resources is just wasting of capital to be invested
and the material to be used. There is an increase in demand for steel structures. This
is because of the ease of construction of steel structures. The erection of steel
structures requires less labor time. The steel structures are also preferred for temporary
structures.
So the application of optimization is very much effective in the case of steel
structures. This paper is an effort to bridge the gap between the industrial
applications of optimization, especially in structural industries. The advancements
in computing technology have enabled to do some complex calculations which
are difficult to solve manually. The genetic algorithm, which is very frequently
used in the field of optimization, is considered for this process. MATLAB is the
software used in this paper to solve the problem. There are three types of structural
