Precast building system offers a wide range of benefits and advantages to the designer to meet all the client`s requirements. The rapid growth in usage of precast systems demands the improvement of its structural behavior when it is subjected to dynamic loads. This Project deals with the analysis and design of Precast Substation building with Crane (5tons capacity) subjected to Dynamic loads due to Earthquake. In order to justify its structural behavior, the cast in-situ structure is also analyzed and compared with precast structure. Hence in this project, the substation building of 78m (length) x 22m (breadth) x 9.6m (height) is designed by considering various loads such as Dead load, Live load, Soil load, Wind load, Seismic load and Crane load as per IS 875: 1987 (Part – I, II, III & V), IS 1893: 2002, IS 456: 2000 and the other guidelines for the crane loads. Seismic loads are calculated using seismic coefficient method and base shear values were obtained. Further the substation building is modeled and analyzed using STAAD.ProV8i software. Both Static and Dynamic analysis (Response Spectrum Analysis) is performed in it. Then from the obtained STAAD.ProV8i results, the various structural elements were designed and quantity estimated. Finally, by using above results, the behavior and quantity comparison between precast and cast in-situ structures were done and conclusion is given.
Key words: Precast structures, substation building with crane loads, seismic resistant structure, dynamic analysis in STAAD.Pro V8i, comparative study between precast and cast insitu structures, connection for precast.
