An Analysis Of Dynamics Of The Reinforced Concrete Frame Under Low-Speed Impulse Loads

The part of damage can cause continuous collapse to building structures as well as heavy loss of lives and property. With social development, more and more building structures can not avoid meeting the action of Low-Speed Impulse Loads which are caused by blast and strike. So the topic of Low-Speed Impulse Loads affecting on buildings is of great interest to researchers and engineers all over the world. But the research in our country is still lagged behind. Dynamic response analysis is researched by numerical simulation, which aims at the frame beam, and a fringe framework and the over all framework.The structure of concrete is molded about dynamic response by using ADINA which affects on the different time of coefficient and elicit the rational coefficient about dynamic response. The frame beam, the fringe framework and the over all frameworks are calculated by PKPM. Reinforcement beams and columns are obtained using PKPM. Reinforced concrete frame beam, the fringe framework and the overall framework are simplified molar focus of mode and obtain the middle-of-bearing column and the bottom of the axial force. The frame beam, the fringe framework and the over all frameworks are calculated by DAINA which elicits the static linear and nonlinear static displacement. It is counted about dynamic displacement and acceleration, as well as induces the dynamic response coefficient of a different time and response spectra. According to calculational result, the rational dynamic response of coefficient is induced. When the structure is considered about linear and nonlinear problem, the dynamic response coefficients are adopted to relatively minor coefficients.
