【摘要】 通过14根矩形截面框架柱在斜向水平荷载作用下的受剪试验,研究其斜向受剪承载力的计算方法。基于单向桁架-拱模型,建立了一个双向桁架-拱模型。为了验证该计算模型的可行性,利用此方法对本试验的14根框架柱及其他文献中的16根框架柱的斜向受剪承载力进行了计算。试验结果和计算值的比值表明,基于双向桁架-拱模型推导的计算公式可以安全估算矩形截面框架柱斜向受剪承载力,满足工程需要。更多还原

【Abstract】 To investigate the calculation method of oblique shear strength of rectangular frame column,a total of 14 specimens under oblique horizontal loads were test.A bilateral truss-arch model was proposed developed on the base of the unilateral truss-arch model.To verify the feasibility of the bilateral truss-arch model,the oblique shear strength of 30 specimens among which 16 specimens were made by other researchers were calculated.The comparison between test results and calculations shows that the developed model is safe to evaluate oblique shear strength of rectangular frame columns subjected to oblique loads,which satisfies the engineering requirement.更多还原
