高层建筑结构选型需求分析

通过对城市社会系统、用户、建筑方案、环境条件等对结构选型的要求与约束等方面的系统分析，辨识出对高层建筑结构选型有重要影响的因素及需通过结构选型来考虑实现的需求，建立了高层建筑结构选型的集成性能需求模型。该模型在广泛的时空系统内揭示了结构选型的需求结构，反映了高层建筑结构及其相关全系统、全寿命过程的各种性能需求，明确了结构选型的任务，为在结构选型过程中全面地考虑各方面的实际需要、减少选型盲目性及系统地研究解决结构选型的其它深层次问题等奠定了基础。

Demanding analysis of structural form selection in high-rise buildings

Firstly,those factors which have important influence upon structural form selection and demandings which were realized by form selection was distinguished through systematically analyzing such factors as the community system,the user,architecture project,environment conditions which restrict form selection.Then the integration performance demanding model of high-rise buildings was founded,which posts the requiring framework of structural form selection in broad space-time.The model also can reflect all kinds of performance demanding of high-rise buildings and its correlative whole system in its whole life process.At last,after nailing down the task of structural form selection,the model can lay down a solid foundation for full considering all aspects of practice demands,reducing the blindness in structural form selection and systematically resolving other profound problems in structural form selection.
