摘　　要：对北方寒冷地区建筑外界面结构进行低能耗优化,可降低建筑的使用能耗,达到节能的目的。进行北方寒冷地区建筑外界面结构低能耗优化时,需要获取建筑外界面结构的应变能、最大位移和平均位移性能,将寒地建筑外界面结构低能耗设计多目标优化问题转化为单目标问题,进行求解即可完成低能耗优化,但传统方法利用自由曲面的方法调整低能耗优化的设计参数,获取多种合理低能耗的寒地建筑外界面曲结构,完成低能耗设计,但不能将低能耗设计多目标优化问题转化为单目标问题,需要针对不同的问题计算其最优解,存在耗时长的弊端。提出改进加权系数的寒地建筑外界面结构低能耗技术设计方法。上述方法先根据非线性大位移理论,推导了建筑外界面膜结构结构的几何非线性有限元方程,并充分考虑寒地地理环境,描述建筑外界面结构的应变能、最大位移和平均位移性能,通过加权系数法将寒地建筑外界面结构低能耗设计多目标优化问题转化为单目标问题,并求解,利用其结果完成了对寒地建筑外界面结构低能耗技术设计。仿真结果表明,选用的方法能够创造良好的建筑环境,有效地节约了能源。It can reduce the energy consumption of architectural and achieve the energy conservation aim to make low energy consumption optimization for architectural surface structure in the northern cold region. In this paper, we proposed a low energy consumption technology design method of architectural surface structure. Firstly, we deduced geometrically nonlinear finite element equation of architectural surface membrane structure according to nonlinear large displacement theory. Then we described the strain energy, maximum displacement and average displacement performance of architectural surface structure, taking full account of geographical condition in cold region. The multi -objective optimization problem was converted into simple objective problem and solved through weighting coefficient method. Finally, we took the advantage of the results to complete low energy consumption technology design for architectural surface structure in cold region. The simulation results show that the method mentioned above can create favorable built environment and save the energy effectively.
