Technologic analysis and comparison of multi-layer steel frame structure

Through technologic analysis and comparison on a teaching building which belongs to multi-layer steel frame structure,the author discusses about design methods of multi-layer steel frame structure and reasonability of the skill.It also points out that the above structure has many merits,such as environmental protecting,light,and it needs short construction time.However,it's cost is relatively high and thus the focal point of study later is to seek balance point between advanced technology and lower cost.
