Assumed structural damping ratios 结构阻尼比假定
Strength Design 强度设计 2.0% and 4.0% for 100-year winds
Serviceability Design (checking deflection)使用阶段品质验算 (位移 验算) ▪ 2.0% for 50-year winds without auxiliary dampers (Chinese Standard);
Serviceability Design (checking occupants’ comfort level)使用阶段 品质验算 (居住舒适性验算) ▪ 1.0% for 1 to 10-year winds without auxiliary dampers;

Key Results 主要结果
Serviceability Design 使用阶段品质验算 – For checking deflection 位移验算 58m/s (10-minute mean) at 500m reference height for a 50-year return period (Chinese standard) ; or 五十年回归期，500米处参考风速为58m/s。（中国标准） – For occupants’ comfort (building motion)居住舒适性验算 1-year return period speed for events including typhoon, and 1 to 10-year return period speed for events excluding typhoon. 包括台风情况时考虑一年回归期；不包括台风情况时考虑一年至十年回归 期。
