高层建筑地震作用下高阶振型影响的近似计算

The high building high level earthquake type approximate calculation under earthquake

介绍了振型分解反应谱法,探讨了需要考虑的振型数量及变形增大系数,指出通过对振型分解反应谱法计算结果乘以一个增大系数来近似考虑更高阶振型影响的做法,具有计算简单、理论清晰且偏于安全的特点。

The paper introduces to flap the type resolve the reaction chart method, inquirys to be considered of flap the type quantity and transform the aggrandizement coefficient, points out to pass to flap the type resolve the reaction chart method the calculation the result multiplies like with an aggrandizement coefficient the higher rank in consideration flaps the way of doing that type influence has the calculation simple, theory clear and safe characteristics.
