When deck and house joists are parallel, screw a metal tie to the side of a house joist and another to a deck joist with structural screws. By code, alldecksmust be designed and built to resist lateral loads, the forces that tend to pull a deck away from a house. Since 2009, the I...
Bracing in the form of cross-frames and diaphragms are often provided at locations along the bridge length to reduce the unbraced length and increase the buckling capacity. Although they are not currently relied upon for bracing, permanent metal deck forms (PMDF) are frequently used to support ...
New design equations for calculating the lateral-torsional buck ling moment resistances of stepped I-section beams with/without continuous lateral top-flange bracing subjected to a point load, a series of point loads, and a uniformly dis... JS Park 被引量: 0发表: 2006年 加载更多来源...
This approach required extensive strengthening or complete replacement of numerous components, including the bearings, truss members, and connections; bottom lateral bracing and connections; and the entire deck system, pier columns, webwalls, footings, and distribution blocks. Memphis braces for a lot ...
lateral bracingcompact sectionsfinite element analysisbeam designContinuous multispan beams in bridges experiences high negative moment at interior supports and the top flanges of these beams are laterally braced due to the concrete slab or steel deck above it. The negative moment can be resisted by...
the cross-braces secure the tank against vertical movement produced by over-turning forces or an uplift force on the tank shell such as can result from internal pressure or product load. The elongated cross-braces 35 and 43 are arranged in X bracing arrangement with the ends joined to the ta...

BracingContinuous multi-span steel beams are common along the building and highway systems. Typical construction consists of a concrete slab supported by steel beams. The top flange of the beams is typically braced against lateral movement by the metal deck form or by the concrete slab. Design ...
top lateral bracingWhile steel composite box girder bridges possess considerable torsional stiffness in their final completed stage, the absence of the deck slab during construction can make them vulnerable to large torsional deformations and instability. Recent collapse of the...
The beams have been subjected to a concentrated load or a uniformly distributed load applied at top flange and end moments. New moment gradient factors for prismatic or stepped beams with continuous lateral top flange bracing have been developed using the results of the FEM investigation. In all ...
