Based on the static load test of a simply supported steel box girder suspension bridge spanning the Yangtze River with a main span of 800 m, the strength and stiffness of the control section of the bridge structure under static load are analyzed to evaluate the bearing capacity performance of the bridge.
Through the finite element analysis and simulation of the static load state of the bridge, the measured structural response of the bridge under the actual static load is compared with the finite element simulation analysis results. The results show that the strength and stiffness of the test control section of the extra-large bridge meet the requirements of the specification , the stress condition is consistent with the theoretical simulation results, and the overall performance of the bridge is good.
Wind Resistance
Steel structure building has the performance of high strength, solid rigidity and good deformation capacity, can resist strong wind for 50m/s.
·Durable
The steel material will be painted or galvanized as customers' requirement to be more anticorrosion and rustproof, the lifespan of the structure can be reach to 50~70 years.
·Heat Insulation
Sandwich panel can improve the insulation performance of the building, effectively avoid the phenomenon of "cold bridge" wall
·Environment Protection
Little waste for pollution in construction, 100% steel structure materials can be recycled, most of other related materials also can be recycled.
