This project is to study, experimentally on a shaking table, the effects of connection flexibility on the seismic response of semi- rigid steel frames and to explore the applicability and limitation of such frames in low and medium rise structures. It has been widely known that connection flexibility tends to elongate the natural period of a structure and thus might reduce the seismic response. To date, however, no such experimental information exists to enable us to understand the true dynamic response behavior of semi-rigid steel structures. The research will identify parameters to control and reduce seismic responses of semi-rigid frame structures.

本项目是在振动台上进行试验研究， 连接柔性对半刚性框架结构地震反应的影响 刚性钢框架，并探讨适用性和局限性， 这种框架在低层和中层结构中。 众所周知，连接灵活性倾向于 延长结构的自然周期，从而可能减少 地震反应 然而，到目前为止，还没有这样的实验。 信息的存在使我们能够了解真正的动态 半刚性钢结构的响应特性。 该研究将确定控制和减少地震的参数 半刚性框架结构的响应。
