Overstrength and ductility factors of XBF structures with pinned and fixed supports

چکیده
Abstract In today's time, most seismic design codes are based on a linear elastic force-based approach that includes the nonlinear response (ductility and overstrength) of structure through reduction factor (named behavior q in Eurocode 8 [EC8]). However, use prescribed -factor is constant for given structural system may fail providing structures with same risk level. This paper focuses estimation actual values X-braced steel frames (XBFs) designed according to European comparing these those suggested EC8. For this purpose, pushover analysis has been performed. The effects specific parameters, such as stories number, brace slenderness ratio, local members, support type, evaluated. results show important parameter affects while type less effect factor. Furthermore, strength criterion proposed implicitly ensure value conservative.

Stability and Ductility of Steel Structures
The objective of this paper is to provide a review of the Direct Strength Method for coldformed steel design. The Direct Strength Method was formally adopted in North American design specifications in 2004 as an alternative to the traditional Effective Width Method. The appendix of this paper provides an excerpt from the North American Specification which provides the Direct Strength Method equ...
