Abstract: An office building is divided into office and conference center by the seismic joint. The structure system of office building is thirteen layer frame-shear wall structure of. This building has two layer basements. The steel reinforced concrete is used in frame of entrance hall because the frame span is 15.2m. Underground and ground layer floor slab adopt the cast-in-situ hollow concrete floor system. The foundation of building is cast-in-place bored embedded rock pile and cast-in-place pile post grouting technology is used for improving bearing capacity of single pile. This paper introduces the structure layout and structural design difficult points. The structural calculation index is analyzed and optimized.  The cast-in-place concrete hollow floor structure design and reinforced concrete bored piles and cast-in-place pile post grouting technology are discussed.

Keywords: steel reinforced concrete;cast-in-situ hollow concrete floor system;cast-in-place pile post grouting
