The study of longitudinal cracking in continuous composite beams
Abstract:According to the experiment of seven continuous composite beams and some data which was related to it,the reason lead to longitudinal cracking in continuous composite beams and the principal infiuence of it were analysed in this paper.On the basis of it,the formulas of calculating crack load and ratio of stirrup disposition were gained.
Keywords:continuous composite beams  longitudinal cracking load  ratio of stirrup disposition
