The main aim of the present study is to achieve optimum design of reinforced concrete (RC) plane moment frames using bat algorithm (BA) which is a newly developed meta-heuristic optimization algorithm based on the echolocation behaviour of bats. The objective function is the total cost of the frame and the design constraints are checked during the optimization process based on ACI 318-08 code. ...

The seismic performance of elliptic braced moment resisting frame (ELBRF) is assessed here and is found that the structural behavior is improved and is of free of architectural space. The demand for seismic performance of ELBRF is estimated through conventional pushover methods of 3, 5, 7, and 10-story ELBRF frames and they are compared with special moment resisting frames (SMRF) and X-Braced C...

This paper proposes a GA-based reduced search space technique (GA-RSS) for the optimal design of steel moment frames. It tries to reduce the computation time by focusing the search around the boundaries of the constraints, using a ranking-based constraint handling to enhance the efficiency of the algorithm. This attempt to reduce the search space is due to the fact that in most optimization pro...

Precast Steel-Reinforced Concrete (PSRC) structural frame systems for moment-resisting, comprised of Prefabricated Steel (S) girders and Reinforced Cement (RCC) columns. This system has the advantage inherent stiffness damping during a seismic event. PSRC’s moment-resisting is also known its construction efficiency, lightweight, low cost. Earlier investigations have shown PSRC helpful in design...

Recent earthquakes have enforced the engineering community to design seismically more efficient buildings through energy dissipation systems. For this purpose, paper investigates seismic behavior of a high-rise building with series base isolation Firstly, 20-storey steel frame is selected as fixed-base building, and then equipped lead rubber bearings (LRBs). In modelling LRB, period alternative...

The fundamental period of vibration appears to be one of the most critical parameters for the seismic design of buildings because it strongly affects the destructive impact of the seismic forces. In this article, important research data (entitled FP4026 Research Database (Fundamental Period-4026 cases of infilled frames) based on a detailed and in-depth analytical research on the fundamental pe...

The Klandasan Parking Building (GPK) is an 8-story parking built in Balikpapan that serves as vehicle and uses a conventional structure system (columns, beams, plates) where the highest beam about 800 mm. To maximize clearance of each story, alternative planned by removing beams called flat slabs. new plan conducted modifying into dual which consists Intermediate Moment Resisting Frame, plate w...

Abstract The aim of the present research is to increasing stiffness structure against lateral loading. In study increase we have four load resisting elements are considered such as shear wall, core bracing system and tube in compare all models with bare frame structure. Here an ordinary moment building G+13 stories located over a medium soil considered. symmetric number bays will be kept 5 alon...
