Seismic Design of Symbolic Landscape Towerin Urban Green Spaces for Emergency Avoidance

为了确保应急避险的城市绿地标志性景观塔抗震设计在城市绿地中能够发挥重要作用,需要进一步研究城市绿地景观塔的抗震设计内容。提出基于Logistic模型的城市绿地景观塔抗震设计方法,该方法介绍用于应急避险的城市绿地的规划、用于应急避险的城市绿地标志性景观塔中功能模块的作用、城市绿地标志性景观塔抗震设计理念,并分析Logistic模型在城市绿地景观塔抗震设计中的应用。结合模拟工程实例分析,利用抗震系数和地震灾害影响因子分析城市绿地标志性景观塔的抗震性能以及抗震设计是否合理。实例结果证明,城市绿地标志性景观塔的抗震性能较好,并且抗震设计具有合理性,能够符合应急避险绿地要求,具有较好景观效果。

To ensure the effectiveness of symbolic towers in urban green spaces as regards emergency avoidance,the seismic design of such landscape towers should be further studied.In this work,a seismic design method based on the logistic model is proposed.This method introduces the planning of urban green space used as emergency shelter and the role of function module in the landmark tower of urban green space.The concept of seismic design of urban green space symbolic landscape tower and the application of the logistic model in the seismic design of such towers were analyzed.In addition to the analysis of a simulated engineering example,the seismic performance and seismic design of the symbolic landscape tower of urban green spaces were analyzed.The results showed that the seismic performance of the symbolic landscape tower is good,and the seismic design is reasonable;moreover,the design can meet the requirements of emergency green space and has good landscape effect.
