【摘要】 本文对强度相关公式的理论做了较详细地阐述。对砖砌体的截面弯曲塑性进行了理论探索,提出了截面塑性深度系数μ和截面弯曲塑性系数η,并从而引出柱弯曲塑性系数概念。应用偏压砖柱试验数据,归纳出砖柱的弯曲塑性系数γ_塑的数值。最后将砖柱的弯曲弹性系数γ_弹与弯曲塑性系数γ_塑合并为γ,使强度相关公式进一步得到简化。其计算结果与试验结果符合较好。更多还原

【Abstract】 In this paper, the theory of strength correlation formula is described in detail and the sectional bending plasticity of brickwork is investigated. From the strength correlation formula the concept of bending plasticity coefficient of column γplas, is introduced and its values are obtained from test results. Finally, the coefficient of bending elasticity and plasticity are combined into one coefficient γ so as to make the correlation formula simpler. The calculated results agree well with those of the test.更多还原
