Abstract: A simplified method is proposed for evaluating the stability of multistory, steel, semibraced, and unbraced frames with semirigid connections. The proposed method decomposes a frame into individual stories and evaluates ...

Abstract: The performance of an intercooled turbofan engine is analyzed by multidisciplinary optimization. A model for making preliminary simplified analysis of the mechanical design of the engine is coupled ...

Abstract: This paper presents an efficient manual design approach, to obtain a near least-weight design by following prescribed procedures, for the preliminary design of long-span king-post steel truss systems. An innovative simplified ...

Abstract: This paper presents an efficient computer‐automated method for the optimum design of steel frameworks accounting for the behavior of semirigid connections. The method explicitly accounts for both connections and members ...

Abstract: This paper presents a multicriteria optimization method for the performance-based seismic design of steel building frameworks under (equivalent static) seismic loading. Minimizing structural cost (interpreted as structural ...

Abstract: This paper presents the effect of temperature and tensile-strain rate on the mechanical properties of high-strength low-alloy structural Q460 steel. Standard coupon tensile tests were carried out to obtain the stress-strain ...

Abstract: The purpose of this study was to quantify the weathering-aging degree by establishing a conversion relationship with standard pressure-aging vessel (PAV) aging, thus guiding the selection of environmental parameters in the ...

Abstract: To better understand the mechanical behavior of cold-formed steel (CFS) quadruple-limb built-up box-section (QBB) columns associated with flexural buckling, 12 axial compression tests with different slenderness ratios and ...

Abstract: The objective of this paper is to to ascertain the reliable mechanical properties of cold-formed Q345 steel at elevated temperatures while considerting the effects of tensile strain rate and specimen width. This paper ...

Abstract: In order to study the influence of different casting temperatures and curing conditions on the hydration reaction, strength, and micropore structure of concrete cured in a low negative temperature environment, a hydration ...
