中文摘要:
      通过考虑波形钢腹板的折迭效应,提出应用二维折迭联结单元来近似模拟其三维折迭效应的计算方法,建立了简单的二维有限元模型.并应用该方法计算了两个不同比例尺寸的波形钢腹板预应力混凝土试验梁,通过对计算结果与试验结果的比较,证实了这种方法的可行性.应用提出的计算模型,对波形钢腹板PC梁的截面应力、波形钢腹板的受力性能、横向加劲对受力的影响等进行了分析.
英文摘要:
      Based on the analysis of the accordion effect of the corrugated steel web,a simple approach is proposed to account for the three-dimensional accordion effect within a two-dimensional finite element analysis.Viability of the approach is demonstrated through comparison of experimental and numerical(results) for large-and small-scale specimens of prestressed concrete beams with a corrugated steel web.Using the approached two-dimensional finite element models,the strains of the cross sections,the behaviors of the corrugated steel webs and the effect of the transverse bracing members are discussed.
