摘要

在本研究中，分析了倾斜和正交风条件下的荷载模式，以确定响应增加或减少的程度。随着建筑物高度的增加，其受
风影响的脆弱性也会增加。规范和标准使用“阵风荷载系数”（GLF）方法来估计 0、45 和 90 度对高层结构的动态影响。在
风荷载的实际情况下，这些条件不适用于强风响应。为了获得其他倾斜风向的响应，假设各种类型的荷载模式施加风荷载。
对于强风下结构的动力响应分析，使用频域的谱响应方法或时域运动方程的逐步积分。本文旨在就高层建筑动态风荷载的阵
风响应系数（GRF），对顺风和横风响应中的各种斜风和正交风荷载模式进行比较。在这项研究中，对仰光地区和沿海地区的
强风模型进行了分析。然后，对强风作用下的最大结构响应进行了比较。
