This paper presents an investigation on the seismic behavior of steel moment frames with mechanical hinge beam-to-column connections. The connection uses a mechanical hinge to carry shear force and a pair of buckling-restrained steel plates bolted to the beam flange to transfer bending moment. The moment-rotation behavior of the connection was theoretically studied. A nonlinear numerical model for steel moment frames under strong earthquakes was developed and validated using a shaking table test of an 18-story steel moment frame at the E-Defense facility. Then, nonlinear static and time-history analyses were conducted to compare the seismic behavior of a conventional steel moment frame and three innovative steel frames equipped mechanical hinge connections in terms of roof displacement, base shear, inter-story drift ratio, and plastic hinge rotation.

具有机械铰链梁柱连接的钢矩框架的抗震性能

本文介绍了具有机械铰链梁柱连接的钢弯矩框架的抗震性能研究。该连接使用机械铰链承载剪切力，并使用螺栓连接到梁翼缘上的一对屈曲约束钢板来传递弯矩。理论上研究了连接的力矩-旋转行为。在 E-Defense 设施中，使用 18 层钢弯矩框架的振动台试验开发并验证了强地震下钢弯矩框架的非线性数值模型。然后，进行了非线性静力和时程分析，比较了传统钢框架和三个配备机械铰链的创新钢框架在屋顶位移、基础剪力、层间位移比、
