摘要
介绍了某工业遗址改造成的观景平台受力特性。该观景平台为冬奥广场景观工程的一部分,外形要求高,故结构体系较为不利。通过对该观景平台结构进行有限元建模分析,经过不同的结构方案对比,选出较为合理的方案后,通过加速度时程法进行舒适度分析,得出结论:对于工业遗址改造项目,既有建筑物的基础往往可以得到利用;经过优化设计,长悬臂平台能满足舒适度的要求;观景平台设计时,要充分重视荷载不均匀分布带来的不利影响。
The mechanical characteristics of the viewing platform transformed from an industrial site were introduced. The viewing platform is part of the Winter Olympics landscape project,because the appearance has high demand,so the structure of the system is more adverse. Through the finite element analysis of the structure of the viewing platform and the comparison of different structural schemes,after selecting a more reasonable scheme,the comfort analysis was carried out by the acceleration time history method,and finally the conclusions were given: for industrial site renovation project,the existing building foundation can be always used; through the optimization design,the long cantilever platform can meet the comfort requirements; the design of viewing platform should pay full attention to the adverse effects of uneven load distribution.
