EFFECT OF FORK RESTRAINT OF COLUMN ON LATERAL BUCKLING BEHAVIOR FOR H-SHAPED STEEL BEAMS WITH CONTINUOUS BRACES UNDER FLEXURAL MOMENT GRADIENT
نویسندگان
چکیده
When a steel moment-resisting frame deforms horizontally, H-shaped beams are subjected to the flexural moment gradient. Generally, rigidly connected box section columns possessing large fork restraint. Further, continuous braces on top flange effectively prevent lateral buckling. In this paper, buckling behavior of continuously braced with restraint under gradient is clarified theoretically and analytically. Additionally, elastoplastic stresses force rotational evaluated, reflecting constraint at beam end.

Experimental Investigation on Seismic Behavior of Steel Truss-RC Column Hybrid Structure with Steel Diagonal Braces
This paper aims to provide an experimental support on seismic performance evaluation of the steel braced truss-RC (reinforced concrete) column hybrid structure, which could be applied as the air-cooled supporting structural system in large-capacity thermal power plants located in strong earthquake prone regions. A series of pseudo-dynamic tests (PDTs) and quasi-static tests (QSTs) were performe...
متن کاملComparison of Progressive Collapse Capacity of Steel Moment Resisting Frames and Dual Systems with Buckling Retrained Braces
Progressive collapse is a condition where local failure of a primary structural component leads to the collapse of neighboring members and the whole structure, consequently. In this paper, the progressive collapse potential of seismically designed steel dual systems with buckling restrained braces is investigated using the alternate path method, and their performances are compared with those of...

متن کاملLateral Torsional Buckling of Steel Thin-Walled Beams with Lateral Restraints
Metal thin-walled members have been widely used in building industry. Usually they are utilized as purlins, girts or ceiling beams. Due to slenderness of thin-walled cross-sections these structural members are prone to stability problems (e.g. flexural buckling, lateral torsional buckling). If buckling is not constructionally prevented their resistance is limited by buckling strength. In practi...
متن کاملBehavior of Steel–Concrete Composite Beams with Corroded Shear Studs Under Negative Bending Moment
The behavior of corroded steel–concrete composite beams under hogging moment was studied by experimental investigation and theoretical analysis. A total of eight specimens, six of which had corroded shear studs, were tested. The corrosion rate of studs ranged from 0 to approximately 50%. The constant-current accelerated corrosion method was adopted to accelerate the corrosion process. The loadi...
