EXPERIMENTAL STUDY ON SHEAR-BEARING CAPACITY OF COMPOSITE HSHP CONCRETE ENCASED STEEL BEAMS
Based on experimental study on composite HSHP concrete encased steel beams,the failure feature of diagonal section for the composite beams is analyzed. By studying mechanical mechanism, it is indicated that arch mode can be used to analyze shearbearing capacity of the composite beams. Several factors that affect diagonal section shear-bearing capacity of the composite beams are discussed. Resistance coefficient for various parts of the composite beams under different loads is determined and the formulas of diagonal section shear-bearing capacity for the composite beams are provided based on test results. In which, axial compressive strength fc of concrete and axial tensile strength fs of steel are replaced by axial tensile strength ft of concrete and shear strength fv of steel respectively, so they can reasonably reflect the influence of concrete strength and steel size change on shear capacity of the composite beams and make it design more reasonable. Research results may be useful for the analysis and design of composite HSHP concrete encased steel beams.
