【摘要】 考虑了材料非线性,对大跨空间网格结构在多点和一致输入下进行动力响应分析。通过对极限加速度峰值、最大节点位移时程、塑性杆件数量和分布及网壳破坏形态这些重要参数的统计、对比、分析和归纳,剖析了大跨空间网格结构在多点输入和一致输入下的强度破坏机理。更多还原

【Abstract】 The elastoplastic dynamic behaviors of space lattice structures are thoroughly analyzed under multiple support excitation and simple support excitation.Some important parameters such as the utmost peak value of acceleration,time history of high-point displacement,the amount and distribution of elements under plastic,the deformation of shell in ruins are counted,contrasted,analyzed and concluded.Based upon these results,the rules of strength fracture about space lattice structure are studied under multiple support excitation and simple support excitation.更多还原
