【摘要】 在“软化桁架理论”的基础上,本文针对小扭弯比的情况,提出了复合受力下钢筋混凝土构件受力分析的“板-桁模型理论”,并建立了相应的计算方法;理论研究以及与试验结果的对比分析表明,该理论是合理可行的.它是对软化桁架模型理论的完善和深化.此外,本文将T形截面按整体分析,避免了弯矩的分配问题,使理论模型更符合实际情况.更多还原

【Abstract】 Based on the softened truss model theory and a lot of available theoretical results and experimental data, this paper presents the Plate-Truss Model Theory, which can be suitable for bending predominanted reinforced concrete members. The theory is successfully applied to the complete response process analysis for these members under combined bending, shear and torsion. The basic formulas of the model theory have been set up with computer programs compiled. The feasibility of the theory is demonstrated by comparing the calculated values with the experimental results.更多还原
