Abstract: The entrance building of Beijing No.4 subway line has single-layer with 3.400m high. This entwining steel structure consists of beams, columns and slope bars by welding. The building is connected with the existing structure under the ground by the technology of bonded rebar. And the other parts use the strip foundation combining with water-proof slab. According to the calculation and the types of the foundation, we adopt different column base types to convenient the construction ofthe building.
Keywords: entwining steel structure; bonded rebar; welding of steel structure; anchor bolts
