Crack Resistance Analyses on RC Composite Floor Slab Peng Chang 1,a, Qian-Feng Yao 1,b and Aping Wang 1,c 1 School of Civil Engineering and Architecture, Beijing Jiaotong University, Beijing 100044, P.R.China a Champen2003@126.com, bYaoqf808@163.com, camandaqw2002@yahoo.com.cn Keywords: Composite floor slab; Durability of structure; Crack resistance; Maximum tensile stress; Regular service stage Abstract.
A number of structure experiments and experiences from engineering practice show that analysis method on crack resistance of RC composite floor slab in this paper is convenient and effective.
The difference between theoretically value and measured value is not more than 7% in general, which is acceptable in engineering design.
