Abstract:Beijing digital plaza is a doubletowered building which is 137 meters long.The center space of the plaza is an atrium from floor B1 to 4,and two towers are connected by a steel corridor on the 11th floor.The scheme design of structure,linear and nonlinear analysis,the calculation and details solution of single span frame shearwall structure among long space between shear walls,overlength structure without expansion point,the strengthening of locally weak area,the seismic design of the bearings of the corridor and the design of the steel frame of the atrium are mainly presented.
Keywords:doubletowered buildings;single span frame shearwall structure;overlength structure;antiseismic bearing
