Torsional Properties Structural Steel Box Girder For Bridge Construction

Torsional Properties Structural Steel Fabrications Box Girder for Bridge Construction

The section shape of the box beam is the same as that of the usual box section, so it is called a box beam. It is generally composed of a cover plate, a web plate, a bottom plate and a partition plate. Mainly used for large span or load-bearing structures.

When the span of the bridge is large, the box girder is the best structural form, and its closed thin-walled section has high torsional rigidity, which is especially beneficial for curved bridges and bridges with cantilever construction. The top and bottom plates have large areas, can effectively resist positive and negative bending moments and meet the needs of reinforcement, with good dynamic characteristics and small shrinkage deformation values.

The box-shaped section has good bending and torsional properties. The top and bottom plates of the box-shaped section are the main parts of the structure to provide bending resistance. The web of the box girder mainly bears the bending shear stress of the structure and the main tensile stress caused by the torsional shear stress.

Compared with the solid web beam of the same section, it has light weight, less consumables and good bending resistance.

Application:
Box girder is widely used in bridge engineering, and its shear lag effect is a problem that must be considered in design calculation. Affected by the shear lag effect, the stress distribution of the upper and lower flange plates of the box girder is very uneven along the plate width. Usually, the stress near the web is the largest, and its value is much larger than that calculated by the elementary beam.

Brief Introduction of Subsidiaries:

1. Hangzhou FAMOUS Steel Engineering Co.,ltd. focus on the Design & Construction of various Steel Buildings and Structural Steelworks fabrication. The company have received a lot of foreign projects ranging from warehouse buildings, multi-storey apartments, high rise office & hotel buildings, space framing theaters, triangle truss buildings, to steel bridges, handling machinery framing, power plant towers, mining production line steelworks, cement production line steelworks, petro-chemical rackings etc. Basically the company have the full capability to operate various large-scaled projects complex except the simple building project.

2. FASEC (Hangzhou) Window Wall Company specializes in the offer of various aluminum & glass-related products design/manufacture/supply & installation. We have successfully supplied quite a lot of insulated & laminated glass panes, windows, glass doors, curtain walls, partition walls, railings, louvers, grills, metal claddings etc not only in China but also around the world. Australian standard, British Standard, Europe standard, and American standard etc aluminum & glass facade products are in our main research & development range.

3. Hangzhou FASEC Building Material Company play the role of the bridging and lubricating with different customers of new building material requirement for roof wall floor and interiors. Our building material team always are on the way to research and develop new style building material to save cost and time of building industrial customers. USEU Metal factory is its strong manufacturing backup force, and our own engineering team can offer various technical supports too.

FASECBuildings Group have passed by series of certifications like the quality management system (ISO 9001:2008), the Europe product quality control system EN1090, the structural fabrication system certificates of Europe ISO3834 and America AWS D1.1, the Australia AS2047 Glazed Windows Doors Qualifications etc.
