Description

Steel pipe prestressed web composite beam

Technical Field

The utility model belongs to the building field especially relates to a steel pipe prestressing force web combination beam.

Background

The traditional H-shaped steel simply-supported composite beam adopts a flat web plate, the thickness of the web plate is larger due to the structural requirement, the proportion of the web plate to the steel used for the section is usually more than 50%, and the economy is poor; if the middle section corrugated web is adopted, the economy is realized by increasing the height of the beam, the shearing force of the web of the beam is the largest near the support of the beam, and the thinner middle section corrugated web possibly cannot pass the shearing force checking calculation; and because the corrugated web plate at the middle section can not provide in-plane inertia moment, the rigidity of the beam is weaker than that of a flat web plate, and the midspan deflection is larger.
