钢管再生混凝土拱桥拱肋地震响应及抗震性能
Seismic Responses and Anti-seismic Performance of Recycled Concrete-filled Steel-tube Arch Ribs
摘要
Abstract
Anti-seismic performance of the recycled concrete-filled steel-tube arch ribs is studied. The model for a single span and half-through arch bridge is established, and its dynamic characteristics are analyzed. The peaks of the bending moment response and axial force response in different sections of the arch ribs are calculated. Meanwhile, the seismic evaluation curves of the five yielding stages of the arch ribs with different regeneration aggregate replacement rates are obtained. Comparing the relations between the peak of the internal force response and the seismic evaluation curves, the anti-seismic performances of the arch ribs are obtained. Results of computation show that the recycled concrete applied to the steel-tube arch ribs has good anti-seismic performance, and the replacement rate of the recycled aggregate has little influence on the anti-seismic performance of the concrete-filled steel-tube arch ribs.关键词
