| 摘 要： | 通过对榀总体刚度矩阵的子矩阵（ＫＩＩ）的ＬＤＬＴ分解，在求出单榀子结构侧向刚度矩阵时避免了求逆运算，并得出结构内部自由度．对设置的ＬＦ数组的分析，就可任意排列子结构的自由度编号，进行错层结构的空间协同分析，提高了计算机进行高层建筑结构内力计算的效率和精度，扩大了空间协同分析的应用范围．

| Abstract: | By the LDLT decomposition of the sub-martrizKII] of structure's total stiffness martrix,can avoided reverse transformation and got the inter freedom degrees of sturcture when caculating the lateral stiffness martrix in sub-structiure.After analysing the setting up of LF data set,the freedom coding of the sub-structure can be freely arranged and the space-cooperation analgsis of the shifted structure can be makde. Therefore the interforce caculating efficiency and precision of computer in tall-building structure can be improved and the range of space-cooperation analysis can be enlarged. |
