无筋砌体墙抗剪承载力计算方法的比较
|
摘要
收集了106片低周反复荷载作用下无筋砌体墙的抗剪试验数据,将抗剪强度试验结果与砌体结构设计规范(GB50003-2001)和建筑抗震设计规范(GB50011-2001)理论计算结果相比较,并分析了砌体的通缝抗剪强度、正应力、高宽比对无筋砌体墙抗剪强度的影响。结果表明:两种规范计算的抗剪强度大致相同,并且都具有相当的安全度。其中,用建筑抗震设计规范计算砖砌体结构的安全度略大于砌体结构设计规范公式,而用砌体结构设计规范公式计算砌块砌体结构的安全度高于建筑抗震设计规范公式.两公式均没有合理考虑高宽比对砌体抗剪强度的影响,根据收集的试验结果分别回归出了砖砌体和砌块砌体的高宽比影响系数。
About 106 pieces of masonry walls without reinforcement under low reversed cyclic loading were collected.Also,the shear strength test results were compared with masonry structure design codes(GB50003-2001) and anti-seismic design specification(GB50011-2001) the theoretical calculation result.Meanwhile,the influences of straight joints shear strength,aspect ratio and normal stress on the shear strength of masonry walls without reinforcement were analyzed in this paper.Results showed that two standard calculations of shear strength are roughly the same,and quite safe.Among them,the safety degree of anti-seismic design standard calculation with brick masonry structure is slightly greater while masonry structure design standard calculation with block masonry structure is a little higher.Two formulas have no rational consideration of the effect of depth-width ratio on masonry shear strength.Based on the test results,a influence coefficient of depth-width ratio about brick masonry and block masonry were regressed.
