This paper describes shaking table tests of a 1:12 scale model of a special concentrically braced steel frame with pinned connections,which was fabricated according to a one-bay braced frame selected from a typical main factory building of a large thermal power plant.In order to investigate the seismic performance of this type of structure,several ground motion accelerations with different levels for seismic intensityⅧ,based on the Chinese Code for Seismic Design of Buildings,were selected to excite the model.The results show that the design methods of the members and the connections are adequate and that the structural system will perform well in regions of high seismicity.In addition to the tests,numerical simulations were also conducted and the results showed good agreement with the test results.Thus,the numerical model is shown to be accurate and the beam element can be used to model this structural system.
This paper describes shaking table tests of a 1:12 scale model of a special concentrically braced steel frame with pinned connections, which was fabricated according to a one-bay braced frame selected from a typical main factory building of a large thermal power plant. order to investigate the seismic performance of this type of structure, several ground motion accelerations with different levels for seismic intensity VIII, based on the Chinese Code for Seismic Design of Buildings, were selected to excite the model. results show that the design methods of the members and the connections are adequate and that the structural system will perform well in the regions of high seismicity. In addition to the tests, numerical simulations were also conducted and the results showed good agreement with the test results .hus, the numerical model is shown to be accurate and the beam element can be used to model this structural system.
