| 中文摘要: |
| 通过理论分析与案例计算，对国标《建筑荷载规范》GB 50009—2012与美标《建筑物和其他结构的最小设计荷载》ASCE7-22中关于风荷载的计算作了对比分析。研究发现二者在基本风速定义、风压计算、风荷载体型系数等参数选取和计算均有较大差异。此外，建筑物高度较低时，美标设计风压明显高于国标，随着高度增加，二者差值逐渐减小。 |
| 英文摘要: |
| Through theoretical analysis and case calculations, a comparative analysis was conducted on the calculation of wind loads in the national standard GB50009-2012 and the American standard ASCE7-22 "Minimum Design Load for Buildings and Other Structures". The study found that there are significant differences between the two in the selection and calculation of parameters such as basic wind speed definition, wind pressure calculation, and wind load shape coefficient. When the height of the building is low, the design wind pressure of the American standard is significantly higher than that of the national standard. As the height increases, the difference between the two gradually decreases. |
