为研究纤维混凝土可更换式墙板填充钢框架结构体系的受力性能,对1榀钢框架-预制纤维混凝土抗侧力墙板结构足尺试件进行低周反复荷载作用下的试验研究,待纤维混凝土墙板破坏后更换新的墙板重新加载,测试可更换式结构构造的可靠性,研究结构的破坏机理、滞回性能、延性及变形和耗能性能等。试验结果表明:该结构体系为一种典型的双重抗侧力体系,加载过程呈现出明显的两阶段性,抗侧力墙板先于钢框架破坏,为结构体系的第1道抗震防线,钢框架为结构的第2道抗震防线;抗侧力墙板失效时结构处于可修复水平,更换墙板后结构仍保持相同的抗侧力水平。
In order to study the mechanical behavior of the FRP-filled steel frame structure system with steel-framed panels, the experimental study of the full-scale specimens with 1 × steel frame-prefabricated fiber reinforced concrete Replacement of the new wallboard after the failure of the fiber concrete wallboard is reloaded, the reliability of the replaceable structure test is tested, the failure mechanism of the structure, the hysteresis performance, the ductility and the deformation and energy dissipation performance are studied. The test results show that the structure is a typical double anti-side force system, the loading process shows a clear two-stage, the anti-side force of the wall panels prior to the destruction of the steel frame for the structural system of the first a line of defense, steel The frame is the second anti-seismic line of the structure. When the anti-side-force panel fails, the structure is at a repairable level, and the structure still maintains the same anti-side force level after replacing the panel.
