【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。
[Abstract]:In order to reduce the energy consumption of buildings and achieve the purpose of energy saving, the low energy consumption optimization of the outer interface structure of buildings in the cold area of northern China can be carried out.The strain energy, maximum displacement and average displacement of the outer interface structure of the building should be obtained when low energy consumption is used to optimize the outer structure of the building in the cold area of the north.The multi-objective optimization problem for low energy consumption design of the outer interface structure of cold buildings is transformed into a single objective problem, and the low energy consumption optimization can be achieved by solving the problem. However, the traditional method adjusts the design parameters of the low energy consumption optimization by using the free-form surface method.A variety of rational and low energy consumption curved structures of the outer interface of cold buildings are obtained to complete the low energy consumption design. However, the multi-objective optimization problem of low energy consumption design cannot be transformed into a single objective problem, and the optimal solution should be calculated for different problems.There is a long drawback.A low energy consumption design method for the outer interface structure of cold area building is presented in this paper, which is based on the improved weighting coefficient.Based on the nonlinear large displacement theory, the geometric nonlinear finite element equations of the external membrane structure are derived, and the strain energy of the external interface structure is described by taking the cold geographical environment into account.The multi-objective optimization problem of low energy consumption design of outer interface structure in cold area is transformed into a single objective problem by the method of weighted coefficient, and the maximum displacement and average displacement performance are solved.Based on the results, the low energy consumption technology of the outer interface structure of cold buildings is designed.The simulation results show that the method can create a good building environment and save energy effectively.
