基于抗震约束的园林建筑规划模型设计

Planning Model Design of Landscape Architecture Considering Seismic Constraints

园林建筑在受到地震作用时会受到一定的抗震约束,其中园林建筑的自振频率对园林建筑稳定性影响强烈,因此设计考虑抗震约束的园林建筑规划模型,通过设定频率禁区方式,约束园林建筑受到地震影响产生的较高自振频率;在此基础上,通过增加园林建筑框架柱截面面积方式构建考虑自振频率的园林建筑规划模型,并采用最小二乘法获取园林建筑抗震能力估计函数,实现对园林建筑结构的抗震能力计算。通过受力分析园林建筑墙体可知,在墙体顶部添加水平载荷和分配梁,可增加园林建筑的抗震性。仿真实验结果表明,所设计模型的园林建筑规划效果满意度高,且规划后园林建筑梁中、左墙体和右墙体结构在不同地震烈度下的损伤度低,表明考虑抗震约束的园林建筑规划模型的园林建筑规划结果佳、园林建筑抗震性强。

Garden architecture will be subject to certain seismic constraints when it is affected by earthquake.The natural vibration frequency of garden architecture has a strong influence on the stability of garden architecture.Therefore,the design considers the seismic constraint of the garden architecture planning model.On this basis,a garden building planning model considering natural vibration frequency is constructed by increasing the cross-section area of the frame column of the garden building,and the seismic capacity estimation function of the garden building is obtained by using the least square method,so as to calculate the seismic capacity of the garden building structure.According to the stress analysis of garden building wall,adding horizontal load and distributing beam to the top of the wall can increase the seismic resistance of garden building.Simulation experiment results show that the design model of garden building planning effect satisfaction is high,and after the planning of garden building beam,left wall and right wall structure in different seismic intensity of the damage degree is low,it shows that the garden building planning model considering seismic constraints garden building planning results are good,garden building seismic resistance is strong.
