The test results described in Part 1 of this paper (Lee and Bruneau, 2008) on twelve steel built-up laced members (BLMs) subjected to quasi-static loading are analyzed to provide better knowledge on their seismic behavior. Strength capacity of the BLM specimens is correlated with the strength predicted by the AISC LRFD Specifi cations. Assessments of hysteretic properties such as ductility capa...

Design requirements now appear in the 2005 AISC Seismic Provisions for Structural Steel Buildings (AISC, 2005b), referred to herein as The Provisions, for steel plate shear walls (SPSWs) that are designed such that their web plates buckle in shear and develop diagonal tension fi eld action when resisting lateral loads. Energy dissipation and ductility during seismic events is principally achiev...

BACKGROUND Primary sclerosing cholangitis (PSC) and autoimmune sclerosing cholangitis (AISC) are related, but distinct chronic liver diseases. PSC is associated with a high prevalence of ulcerative colitis while the intestinal inflammation associated with AISC is less well characterised. AIMS To assess and contrast aspects of intestinal inflammation in patients with AISC and PSC and compare t...

This paper reviews contemporary rules in CSA S16:19, AISC 360-16 and EN 1994-1-1 for concrete-filled hollow structural sections (HSS), covering materials, cross-section classification, concentrically loaded columns. Results from 453 tests on axially compressed HSS members are compared to predicted strengths using current (CSA 1994-1-1) recommended S16 design equations (with limits of validity),...

In this study, the optimum design of a three-dimensional framed steel structure subjected to blast loading is considered. The main idea research develop practical formulation for optimization problem and study effect including loads in process. formulated minimize total weight American Institution Steel Construction (AISC) strength requirements displacement constraints. variables beams columns ...

Current design standards for stainless steel such as ASCE 8-02 and EN 1993-1-4 prescribe provisions the of cross-sections members that account material nonlinearities strain hardening, although these features are not considered in global structures. Recent studies have highlighted need accounting order to efficient safe structures, it is expected forthcoming versions will incorporate updated ru...

Consistent with capacity design principles and requirements of ductile behavior, the 2005 AISC and 2001 CSA seismic design codes require that the intermediate horizontal boundary elements HBEs of steel plate shear walls SPSWs be designed to remain essentially elastic with the exception of plastic hinges at their ends when the infill plates fully yield under seismic loading. However, the unexpec...

Following the Northridge earthquake of 1994, a significant number of steel moment resisting structural systems were damaged. Several studies have been conducted to improve the seismic performance of steel structures and specially their beam-to-column connections. One of the proposed connections for special moment-resisting frames included AISC-358 is Kaiser bolted bracket moment connection, bri...
