Research on Design Method of Test Frame for Building Curtain Wall in Shaking Table Tests
Test frames are often used to simulate the main structure to support the curtain wall in shaking table tests of building curtain walls. Besides, there is a strong correlation of the dynamic response and deformation between the test frame and the curtain wall. To satisfy the test requirements, a design method for test frame was proposed in this paper based on finite element simulation. In this method, the initial test frame was designed according to the dimensions of the curtain wall, the expected table acceleration, and inter-story drift angle firstly. Subsequently, a comprehensive finite element model of the initial test frame and the curtain wall was established, and the Rayleigh damping matrix was constructed from the fundamental frequencies of the two plane directions of the model, forming an equivalent calculation model. Finally, the design parameters of the test frame were adjusted until the test requirements were met, according to the comparison between the calculation results and the expected test indicators. On this basis, a test frame was designed for a glass-stone composite curtain wall to execute shaking table test. The test results show that the inter-story drift angle of the curtain wall and top acceleration of the table can satisfy the test requirements, which verifies the rationality of the design method of test frame. With the increase of the input amplitude of ground motion, the inter-story drift angle of the curtain wall shows a nonlinear increasing. At the same time, the panels, connectors and supporting members of curtain wall were not damaged during the test, which meeting the requirements of the seismic design of the project.
