摘要
超高层建筑结构设计中由于受到剪切变形弹力作用的影响,产生线性梁柱动力弹塑性应变力,影响结构强度。提出一种考虑剪切变形弹性修正的超高层结构设计方法。进行了超高层建筑钢结构剪切变形弹性修正应力拟合模型分析,在各种尺寸下分析梁的荷载位移,由Monter Carlo方法在试件截面进行劈裂破坏面的惩罚约束,得到超高层建筑钢梁结构抗剪连接梁应力-应变全曲线,然后进行了超高层建筑的钢梁结构优化设计。实验结果表明,采用该模型能有效提高超高层钢梁结构的受力强度,实现剪切变形弹性修正,提高超高层建筑的强度和可靠性。
Due to the influence of shear deformation and elastic force in the structural design of a highrisebuilding, the dynamic elastic plastic strain of linear beam column is generated, which affects thestructural strength. A new method for the design of high rise structures considering shear deformationelastic correction is proposed. The stress fitting model analysis of shear deformation of high rise buildingsteel structure is carried out, and the load displacement of the beam is analyzed by Carlo Monter method,and the shear strength of the steel beam is obtained by the method. The experimental results show thatthe model can effectively improve the strength of the structure of the high - rise steel structure, realizethe shear deformation elastic correction, improve the strength and reliability of the high - rise building.
