Abstract
It is necessary to analyze the seismic performance of the structure based on the response of the structure to the seismic wave excitation of the FRP tendon concrete structure model through the shaking table. Based on the study of the mechanical properties of GFRP (Glass Fiber Reinforced Polymer) tendons, this paper uses GFRP tendons as the main beam-column tendons to design and manufacture a three-layer, two-span, and 1/4 scale frame model. Four seismic waves are selected, and the model is subjected to unidirectional, bidirectional, and tridirectional seismic wave excitations under a total of 27 conditions of 4 different acceleration peaks, and the acceleration response of each floor of the model under different conditions is obtained. Through the data processing, the displacement response of each floor of the model and the displacement angle between the floors are further obtained. The seismic behavior of the GFRP reinforced concrete frame structure is studied in combination with the experimental phenomena. The analysis results of this experiment show that the prototype structure can also meet the requirements of small earthquakes and moderate earthquakes Repairable, large earthquake-resistant seismic requirements for waterproofing.
