OPTIMAL SENSOR PLACEMENT FOR MODAL IDENTIFICATION OF A STRAP-BRACED COLD FORMED STEEL FRAME BASED ON IMPROVED GENETIC ALGORITHM
This paper is concerned with the determination of optimal sensor locations for structural modal identification in a strap-braced cold formed steel frame based on an improved genetic algorithm (IGA). Six different optimal sensor placement performance indices have been taken as the fitness functions two based on modal assurance criterion (MAC), two based on maximization of the determinant of a Fi...
متن کاملمدلسازی عددی و عملکرد لرزه‌ای دیوارهای برشی در سازه‌های فولادی سبک با ترکیب مهاربند تسمه فولادی و پوشش پنل گچی
Diagonal Strap bracing is one of the most applicable lateral bracing systems in light steel framing (LSF). In practice, one or more panels of Gypsum Wall Boards (GWBs) is used for the cladding of strap braced frames. Usually, the effect of these GWBs in modelling and design is neglected by designers, but this effect can affect the seismic performance of the system In this paper, firstly, a simp...
متن کاملSeismic design of multi - story cold - formed steel buildings : the CFS - NEES archetype building
Lightweight cold-formed steel (CFS) framing is an effective building solution for low and mid-rise structures. However, systems level response and component contributions as well as their interactions such as those from lateral-load resisting systems, floor diaphragms, studs to track connections, etc., are not fully understood. Existing building codes for the CFS frame buildings are based solel...
متن کاملOn Cold-Formed Steel Construction
Powder-actuated (also referred to as low velocity or powder-driven) fasteners are commonly used to attach cold-formed steel framing members, usually a track, to a concrete or structural steel support. Although commonly used, their behavior is less well understood than other fasteners such as screws, bolts and welds. The AISI Cold-Formed Steel Design Manual does not explicitly address powder act...
متن کاملductility-based seismic design of steel plate shear walls: practical application using standard sections
over the past decade of extensive research works, the thin un-stiffened steel plate shear wall(spsw) has now emerged as a promising lateral load resisting system. considering thedemand of performance-based seismic design (pbsd) philosophy in current and futureseismic design codes, a ductility-based design was recently proposed for spsw systems withpin-connected boundary beams. however, the effe...
