| Abstract: | A test is made to study the occurrence and development of cracks in the concrete flange of composite beams under negative bending. It includes three pieces of simply supported and five pieces of continuous composite beams; each composite beam is consisted of a profile steel, profiled sheet iron, and concrete. The test results show that the factors effected on cracks are complex. Some effective measurements are needed to control the cracks. Moreover, based on the test result, the improved formulae for the minimum reinforcement ratio, the cracking moment, and the maximum crack width are proposed in the paper. The computing results are in good agreement with that of the measurements. |
