講座題目Cold-Formed Steel Structures: Basic Design Method and Recent Research on High-Performance Shear Wall System

講座人:虞誠 教授
講座時間2017615日(星期四)9:00
講座地點:土木工程學院主東301
承辦單位:結構工程學科、建築與土木工程領域
 
講座内容簡介Cold-formed steel (CFS) structure is becoming an attractive choice for mid- and low-rise building in US and worldwide due to its advantages of fast construction, easy transportation, high quality control, and mass production ability. However due to the thin-walled structure nature, CFS structures may tend to buckle in complicated modes and require extensive stability analysis in design.  This presentation will have two parts. In Part I, the basic CFS design theory – effective width method will be introduced. Then a new generation design method – Direct Strength Method will be discussed, its application in a recent clip angle design project will be presented. In the Part II, a review of recent research work on cold-formed steel shear wall using corrugated steel sheathing will be given. The new shear wall system offers higher strength and greater stiffness than the conventional shear wall systems in CFS buildings. The presentation will provide both experimental and analytical investigation of the new shear wall system for low- and mid-rise buildings.
