Analysis up to failure of straight and horizontally curved composite precast beam and cast-in-place slab with partial interaction

الملخص EN

In this study, a nonlinear three-dimensional finite element analysis has been used to predict the load-deflection behavior of horizontally curved composite beams of concrete slab and I-section steel beam with shear connectors using the analysis system computer program (ANSYS V.

9.0 2004).

A comparison is made between the results obtained from the finite element analysis and the available experimental results.

The comparison shows good agreement.

The maximum difference in ultimate loads was (13.2 %).

Parametric study was performed to study the influence of several important parameters on the overall behavior of a horizontally curved composite beam.

These parameters include the curvature (L / R) of the beam, supports conditions and concrete compressive strength.

L / R has significant influence as more and more twisting effects will be introduced.
