Analysis And Study Of Several Problems About Web Light-Gauge Steel Structure System

Web light-gauge steel structure system uses economical materials as load-bearing framework and light wall materials as enclosure. This system has many advantages, such as less steel gravity, good seismic behavior, simple construction, short duration, low comprehensive building cost, fast invest retrieve and so on, which conform to industrialization and sustainable development. This system is used widely in foreign country, but it is just used in China, and codes and specifications do not form a complete set, which seriously influence the spread of this system. In the light of domestic situation, it has a lot of practical meaning to sort foreign study achievements and analyze domestic application situation.The paper sorts foreign computation methods and theories about web light-gauge steel structure system, and analyze reasons of several questions about specific construction, such as cracks of walls and vibration of floors, then bring up reinforcement methods.At the same time, the paper brings up suggestions to the study in this field.
