摘要：The main aim of this project is to develop an interior penalty function (IPF) based algorithm to multi-storeysteel frames for minimum weight of frames. The frames are intended for resisting lateral sway due to seismic loadingalong with gravity forces. Many structural systems are used for resisting seismic (lateral) forces; however steel momentresisting frames (MRF) are considered for the present work. The design methodology incorporates codal provisions ofIS 800-2007, thereby obtains the frames with optimum weight for in-plane moments with lateral support of beamelements. Strength and buckling criteria are considered as behaviour constraints along with side constraints informulating optimization problem. A computer program is developed that uses an interior penalty function (IPF) forweight minimization of two-dimensional moment resisting steel framed structures. The program uses MATLAB,performs one dimensional search, and structural design in an iterative procedure. The design examples have shown thatthe proposed algorithm provides an efficient tool for the practicing structural engineers. The program is applied to 6and 9 storey (4 bays) moment resisting frames (MRFs). The program demonstrated its capability of optimizing theweight of two medium size frames. To obtain member forces in frames an analysis procedure has to be applied.In the present work Equivalent Lateral Force procedure (ELF) and material nonlinear time history analysis (NTH) areapplied and optimum values obtained from both the analyses are compared.
