( China Railway First Survey and Design Institute Group Ltd., Xi'an 710043, China)Abstract: Associated with project case of a large-span conference center in Chongqing, the advantages and disadvantages of the usual structure schemes to solve the large-span problem were pointed out in design of the public building which with special column grid. The beam type, the mechfuucal analysis and the characteristics of the components were discussed in the design process to the steel reinforced concrete beam. The details of the beam-column joint were studied and the engineering implementations which with satisfactory operability were also proposed.
Keywords: steel reinforced concrete beam; structure schemes; large-span; details of the beam-column joint; planting roof
