The effect of the height-to-frame ratio in the cyclic behavior and curve of the frame capacity of a single crater

Abstract

Many of constructional structures are designed in a way that at least go under the pressure of relatively intense loads once in the construct’s lifespan. Along with the progress of earthquake engineering science and emphasis on construct retrofitting against lateral forces, using appropriate systems and safe performance against these forces is needed. Today, all structural engineering science researchers are trying to make a leap forward this scope with studying different kinds of systems. In the science of dynamic of construct, system with one degree of freedom and one crater which includes one flat frame is baseline for starting investigations and calculations. In this article, one metal frame with different ratios of height-to-crater’s length under lateral concentrated force in the ceiling’s balance and also under cyclic loading is placed and performance of this frame in different states in the form of a capacity and Hysteresis curve is investigated. ANSYS software was used for modeling of proposed models and the results were compared with each other.
