Dynamic Properties and Seismic Responses of the Masonry Structure Model Strengthened with BFRP Laminates

Abstract

To study the dynamic properties and seismic responses of masonry structure strengthened with Basalt Fiber Reinforced Plastic (BFRP) laminates, modal experiment and shaking table test were performed on a two-storey and two-bay masonry structure model involving constructional columns. Through the test, the dynamic properties of reinforced masonry structure were obtained, the development of cracks and degradation of stiffness of the reinforced masonry structure under earthquake were studied and the variations of displacement, acceleration, stress of this structure were analyzed. Based on the modal experiment using the impact hammer test method, a simplified numerical analysis model of the test model was proposed for modal analysis. From the shaking table test, it is concluded that BFRP laminates can slow down the degradation of structural stiffness and the development of cracks effectively, and the masonry structure reinforced with BFRP laminates has excellent seismic performance.
