A new kind of steel-concrete composite beam with notched web is proposed

and the bend and shear behaviors of this composite beam are investigated. First of all

the constitution

bearing characteristics and merits of the steel-concrete composite beam with notched web are introduced; then

a group of formulas about the bending capacity

slip between the steel beam and the concrete flange

and the deflection are introduced; after that

the bending behavior

slip effect and bearing characteristic of the steel-concrete composite beam with notched web are studied on 4 specimens

which are tested by applying two concreted vertical loads on the top of concrete flange. And the finite element model is adopted to analyze the results of the 4 specimens; finally

the reliabilities of the formulas are verified by comparing the results of theoretical formulas

the results of tests and that of finite element analysis. Study shows that the bend behavior and shear behavior are fine

and the popularization of this new kind of composite beam which can be broadly used in building engineering will save the consumption of steel.
