4 composite beams of steel-high strength concrete were tested to investigate their crack resistance. It was found tiny cracks appear firstly on the bottom surface of concrete slab when about 40% of limit load is acting on a beam. Then the cracks increase and further extend out gradually between loading points, and at last, some of them go through the slab from bottom to top. The relationships between strain and load have been obtained for both steel and concrete slab of composite beam, with their bearing mechanisms discussced correspondingly. The formulas to calculate the load causing cracks are given to the beam on elastic basis. The results of calculation and testing show that they are in good conformity to each other. In addition. a width formula is also given to the composite steel-high strength concrete slab.
