Prestressed Steel-Concrete Composite I-Beams with Single and Double Corrugated Web

Composite steel girders with concrete have been used for many years and advances in structural fabrication technology established their optimization. One of the changes I-beams during past few has availability web corrugation. The economic design normally requires thin webs. Moreover, using externally prestressed tendons as a strengthening technique controls deflections stresses. However, this causes shear buckling beams. In study, flexural behavior composite steel-concrete single double corrugated was experimentally numerically investigated. Three simply supported (SCW) (DCW) were tested under four-point loading. beams by straight along full length. experimental results showed that SCW more efficient resistance than DCW same equivalent thickness. ABAQUAS package to simulate nonlinear developed model validated against carry out parametric study order investigate effect various parameters on DCW. Using stiffeners at loading points deviators maintain tendon positions increased beam capacity improved performance.
