Curved beam
- Commodity name： Curved beam
- 产品描述
-
Shaped steel beams are widely used in numerous buildings. By utilizing the compressive action of concrete poured into formwork on the steel beams, the effective height of the beam's cross-section is increased, enhancing the structural rigidity and load-bearing capacity of the steel beams. This approach saves steel and reduces construction costs. Compared to reinforced concrete beams and slabs, shaped steel beams offer advantages such as reduced formwork requirements, fewer embedded parts, lighter self-weight, lower floor-to-floor heights, easier construction, shorter project durations, and simplified installation of pipelines.
Structural characteristics
Steel consumption for steel structures can be reduced by approximately 15%. According to plastic theory calculations, savings can reach 20%-40%. When calculated elastically, the steel consumption for temporary supports installed beneath curved steel beams during construction is about 80% of that without temporary supports.
Beam height can be reduced by 10% to 15%.
Enhanced bending stiffness reduces beam deflection by approximately 30%.
Superior seismic and impact resistance reduces impact coefficients by over 20%.
