工程振动多振源叠加分析

为了解决工业建筑中的振动影响,有必要清楚地了解振动荷载条件。特别是对于多振源振动荷载叠加问题,需要建立合理的振动合成方法。考虑多振源振动相遇时具有的随机特性,依据《建筑结构可靠度设计统一标准》对荷载效应的技术要求,提出一种简单、合理、有效的＂等效幅值公式＂,并与＂茅氏公式＂进行比较。论文提出的等效幅值公式对工程应用具有更广泛的指导意义。

Combination of Multi Source Vibration Response

In order to solve the vibration effects in industrial buildings, the vibration load conditions necessary for understanding and clear. Especially for multi source vibration load superposition problem, need to establish a reasonable method of synthesis of vibration. Considering the multi source vibration met, random vibration synthesis has the. According to the ＂unified standard for reliability design of building structures＂of load effect combination rules, we propose a simple, reasonable, effective ＂equivalent magnitude formula＂, compared with ＂Mao＇s formula＂. Equivalent magnitude formula proposed in this paper has a more extensive guiding significance for engineering applications.
