Design of the Asian Games Historical Exhibition Center in Guangzhou

The structure of the Asian Games Historical Exhibition Center in Guangzhou is complicated space structure with a shear-wall core tube surrounded by frame braced structure and bowl shape structure suspended from the floors.By adjusting relative stiffness between core tube and frame braced structure,and ballasting floor weight,the torsional resistance is assured.The seismic performance is enhanced by installing steel plate along two sides of steel reinforced concrete core tube shear-walls.Core tube foundation design is based on two types of calculation models.Core tube foundation is independently designed in moderate earthquakes,whereas the integral of core tube foundation and frame column foundations connected by foundation beams is considered for strong earthquakes.Foundation bearing capacity of pre-stressed pipe piles are adopted to satisfy the design demands.Pedestrian comfort assessment is made through vibration control by TMD(tuned mass damper)installed under the side of large cantilevered structure and the spiral ramp.'Hollow out' and steel-tube truncated joints meet the requirements of both architectural effects of supporting structure and joint stiffness.Reasons of using sliding lug pin joints suitable to the project are discussed.
