摘要:
通过ANSYS/LSDYNA有限元分析软件建立有黏结预应力混凝土（BPC）框架结构的高精度有限元模型，对BPC框架结构瞬间去柱动力试验进行数值模拟分析。将高精度数值模拟结果与BPC框架子结构倒塌试验数据进行对比，验证其准确性，在此基础上分析了预应力度、预应力筋配筋率、预应力筋布置形式和配重分布位置对BPC结构连续倒塌动力效应的影响。结果表明：预应力度和预应力筋配筋率的增加可以提高结构抗力，但会削弱其变形能力；采用直线型预应力筋布置，其竖向刚度约为抛物线型布置的1.17倍；当配重钢板均分由6等份增加至12等份时，结构的峰值位移减少了21.0%，竖向刚度提升了26.6%；对比两种不同边界条件可知，边界二（真实边柱尺寸）试件的第一峰值位移和平衡位移相较于边界一（放大边柱尺寸）分别提高了17.5%和34.1%；边界一相较于边界二更安全，但会低估结构动力效应；两种边界条件各具优劣，适用于多元研究目标与试验环境，对深化结构抗连续倒塌机理的认识具有重要意义。
Abstract:
A high-precision finite element model of bonded prestressed concrete (BPC) frame structure was established by ANSYS/LS/DYNA finite element analysis software, and the instantaneous column removal dynamic test of BPC frame structure was simulated and analyzed. The accuracy of the highprecision numerical simulation results was verified by comparing with the collapse test data of BPC frame substructure. On this basis, the influences of prestress degree, prestressed reinforcement ratio, prestressed reinforcement arrangement and weight distribution position on the dynamic effect of BPC structure were discussed. The results show that the increase of prestress degree and prestressed reinforcement ratio can improve the resistance but weaken the deformation capacity of the structure. The vertical stiffness of the linear prestressed tendon arrangement is about 1.17 times that of the parabolic arrangement. When the number of equal parts of the counterweight steel plate increases from 6 to 12, the peak displacement of the structure is reduced by 21.0%, and the vertical stiffness is increased by 26.5%. By comparing the two different boundary conditions, it can be seen that the first peak displacement and equilibrium displacement of the specimen with boundary condition two (actual edge column size) are increased by 17.5% and 34.1% respectively compared to those with boundary condition one (enlarged edge column size). The boundary one is safer than boundary two, but it will underestimate the dynamic effect of the structure. The two boundary conditions have their own advantages and disadvantages, which are suitable for multiple research objectives and experimental environments, and are of great significance for deepening the understanding of the mechanism of structural progressive collapse resistance.
