• A finite element model of composite cellular beams with PCHCS was developed. parametric study carried out by geometrical non-linear analyses. Symmetric and asymmetric section were considered. The predominant failure mode the web post buckling. strength not limited only beam. This paper aims to predict ultimate behavior steel–concrete using precast hollow core slabs. is developed analysis. out...

Based on the bending experiment for two-span continuous post-tension beams with unbounded tendons and externally applied CFRP sheets, the analysis of the stress increment of unbonded tendons is monitored in the loading process. Since self-compacting concrete (SCC) is a suitable innovation,, understanding the implementation of this type of concrete on the ultimate unbonded tendon stress is criti...
