Abstract

Optimum design of concrete slab using genetic algorithm Ken Koyama* & Kazuhiko Shikada^ ' Department of Civil Engineering, Shinshu University, 500 Wakasato, Nagano Japan 380 * Tokyo Electronic Power Inc., 1-1-3 Uchisaiwaicho, Chiyoda Ward, Tokyo, 100 ABSTRACT The optimum design of concrete slab is solved and investigated using genetic algorithm. In ordinal optimum design of slabs, the constraints are restricted to the stresses in concrete and reinforcing bars However, in order to obtain durable concrete structures, the constraint for crack width is very important. Adding to this, the variables like spacings of reinforcing bars are usually determined as discrete one. Therefore, the genetic algorithm is useful for this kind of problems. INTRODUCTION The optimum design of civil engineering structures usually has many constraints and sometimes two or more objectives. The objective functions or the constraints or both are generally expressed by nonlinear function of design
