【摘要】 鉴于内存及外部设备的限制，一般在现有国产计算机上进行大量未知数的高层建 筑结构静力与动力分析是困难的。本文采用了以下力学模型处理和程序技巧［ｌ，２］， 较好地克服了上述困难： （１）多层子结构模式装配和多种荷载模式组合； （２）节点位移的主从关系及相应位移规格数的概念，并在多层子结构自动拼装 中实现了多级位移规格数的传递与修改； （３）采用子结构刚度阵静力凝聚及动力程序和静力程序的“接力”方案，传递 先后计算信息； （４）引入等价膜概念，采用简单而又较精确的计算模型． 工程实例计算表明，上述处理是有效的。从而对现有国产计算机适应日益迫切的 高层建筑结构设计起了推动作用。更多还原

【Abstract】 The static and dynamic analyses of tall buildings are performed by so-called general modular analysis technique in which the substructural technique is expanded by means of different module of substructures and loading factors, in addition, the division of whole analysis into separate suc- cessive steps is introduced. Practical engineering examples 5-10 have been studi- ed by this approach on China-made computer TQ-16, which is limited to small core memory and less capability of peripherial devices. Besides that, specific techniques related to this topic including hierarchical1y multi-level substru- ctural modular composition as well as multi-level loading modular combination, multi-level Master-slave relationship of node displace ments, idealization of structure by equivalent membrane, etc. are discussed. Numerical results are given for illustration.更多还原
