【摘要】 本文对陶粒砼剪力墙结构中的连梁采用足尺试件(传统配筋连梁14根,对角斜配筋连梁5根),在低周反复荷载作用下,实测了连梁的受力性能,研究了强屈比、计算剪箍比、名义剪压比和跨高比等因素对连梁破坏形态、滞回延性和耗能性能的影响,并提出连梁强度计算公式。更多还原

【Abstract】 Based on the tests of 14 conventionally reinforced and 5 diagonally reinforced full-sized ceramite concrete coupling beams under reversed low-cyclic loading, this paper studied the effects of various different ratios, such as the ratios of failure shear to yield shear, computed shear to shear resistance, measured failure shear to concrete strength and span to depth, etc., on the failure modes, hysteresis ductility, and energy dissipation of the coupling beams. Formulas for calculating strength of coupling beams were proposed at the end of the paper.更多还原
