Problems solved by technology

This structural model relies on the friction deformation between the steel plates in the prefabricated parts at the joints to simulate the plastic hinge deformation at the beam-column joints, but the reliability of the force transmission in the friction mode is not enough. The quantitative relationship between bending moments will change to a certain extent, making the test results not accurate and reliable

Abstract

The invention discloses an anti-seismic time-history analysis wave selection verification device. The verification device comprises a vibrating table and a single-span single-frame model fixed on thevibrating table; the single-span single-frame model comprises two struts and a plurality of first crossbeams erected between the two struts; both ends of each first crossbeam are hinged to the strutsthrough hinge pieces; and the upper and lower sides of the two ends of each first crossbeam are separately connected with the struts through shape memory alloy screws. According to the anti-seismic time-history analysis wave selection verification device, the single-span single-frame model can quickly return to an original state without causing test damage after each test, repeated tests can be conveniently carried out, a stress-deformation relationship of the device can be kept stable after a plurality of the tests, and the accuracy and reliability of test results are ensured.

Description

technical field [0001] The invention relates to the technical field of seismic time history analysis, in particular to a wave selection verification device for seismic time history analysis. Background technique [0002] Seismic time-history analysis Wave selection research often requires a large number of seismic waves to be input to the structure for statistical analysis of the nonlinear response of the structure. The use of test methods (such as shaking table) means that the response measurement of hundreds of identical structural models under different seismic wave inputs must be completed. Considering that the structure will enter a state of failure during the test, the economic cost of such a large number of model production is unbearable. As a result, it is impossible to use the experimental method to study the wave selection for seismic time-history analysis. [0003] American scholar O'Donnell et al. (2017) used the shaking table test method in the wave selection r...
