The Olympic landscape tower locates in the centre area of Beijing Olympic Park. It's beside the south of North Xindian Village Road. The main building closes to the axis of the landscape Avenue. The building is consisted of 5 single- towers with different diameter and height connected by steel trusses. Each tower is composed of cylindrical body and the crown formed top with landscape hall and platform...
Based on the theory of thin shell, a simplified calculation model is raised to conduct the analysis of the internal force of variable cross-section of shell concrete structure reinforced by ring beams under various loads. The model selects one-sixteenth of a sphere as the computing unit and simplifies the node, transmit only shaft and shear instead of moment. The calculation diagram selects three...
A practical calculating model, based on the fundamental mode generalized force spectrum (FMGFS) obtained in a wind tunnel test and presented practical higher mode generalized force spectrum (HMGFS) model in along-wind direction of lattice tower, is further deduced and proposed to calculate along-wind displacement response of lattice tower. In the proposed model, the contributions of higher vibration...
