Discussion about combination of vibration loads for building engineeringZhang Tongyi1, Xu Jian2, Zhang Song1(1 China IPPR International Engineering Co., Ltd., Beijing 100089, China; 2 China National Machinery Industry Corporation, Beijing 100080, China)Abstract: Two types of load combinations for different checking conditions were proposed, which are combined with some issues about vibration loads in combinations encountered in the preparation of national standards Dynamic load for the design of industrial building and Code for design of vibration control of industrial building. For type 2, the new added combination type, two ways of vibration loads combinations were given, probability of vibration loads and the principle of combination coefficients were discussed. The load combinations proceed in a stage way for two types was proposed. In the first stage, vibration loads combination was promoted to solve the problems of equipments design under serviceability limit states and vibration attenuation products design under ultimate limit states. In the second stage, the existing vibration loads combination effect was adopted to implement all load combinations which can solve the problems of structure design under ultimate limit states and structure deformation. The proposed methods of loads combination can be utilized to design structures under equipment dynamic loads and related products.Keywords: vibration load; equipment; engineering vibration; load combination
