Comparative Research of Chinese and American Standards Based on a Centrally Support Steel Frame
By establishing a typical centrally support steel frame structure,considering the differences in materials and loads between Chinese and American standards,the difference between the two design standards in the steel frame example is sorted out with the component checking ratio as the index.The results show that the yield strength of A36 grade steel is slightly higher than that of Q235 grade steel.There are great differences in the concept of seismic fortification target between Chinese and American standard seismic action parameters.The difference of wind load is mainly due to the different time interval and return period of basic wind speed measurement.In the case of basically the same risk level,the component checking ratio of the same structure under the Chinese standard is relatively low.
