简述某60m高、180m长大型格构柱广告牌工程概况。本次设计在保证该结构使用功能即达到展示效果的前提下,以确保最佳综合经济指标为目的。设计过程中分别利用3D3S和SAP2000两种结构计算软件,在不同荷载工况作用下设计不同形式格构柱方案进行横向对比,同时增加设置预应力拉锁的格构柱设计方案进行纵向对比并选出最优方案。本次设计可以为类似工程在结构设计选型上提供参考。
A brief overview of a 60m high, 180m long large column billboard project overview. The design in ensuring the use of the structure that is to achieve the display effect of the premise, to ensure the best comprehensive economic indicators for the purpose. In the process of design, 3D3S and SAP2000 are respectively used to calculate the cross-sectional contrast of different types of lattice columns under different load conditions. At the same time, the lattice column design with pre-stressed zipper is added for vertical comparison and selected best plan. This design can provide reference for similar projects in the selection of structural design.
