Abstract

Recently, with the increase in the height of buildings, the need to use systems resistant to lateral forces such as earthquakes and strong winds has become more pronounced, and the lack of attention to them will lead to damage. Among the systems resistant to dynamic loads, the piston-shape bracing system has an important role in the stability of structures and the control of dynamic responses, such as displacement and acceleration, and by absorbing energy, the structure is protected against various excitations and prevent serious damage to the structure. In this paper, a new piston-shaped system consisting of two outer and inner tubes and several parallel semi-circular plates attached to them is considered, which exhibits good resistance to compression, tensile and buckling, and can be mounted in a variety of concentric, eccentric and other ways, reduce the lateral forces to the structure by dissipating energy. In this paper, the behavior of a steel frame using the piston-shaped bracing system against dynamic loads is investigated and some of its dynamic responses are controlled. Five types of pistons are designed for this purpose, each placed in a one span steel frame. After modeling all five types of braces, the results are compared with each other. The main purpose of this study will be to investigate the efficiency of controlling dynamic responses such as displacement, velocity and acceleration and buckling of the piston-shaped brace to minimize the damage caused by lateral loads applied to the structure.
