Improvement in Longitudinal Shear Capacity Estimations Difference for Profiled Composite Slab

lope-intercept and partial shear connection methods are two known methods for the determination of the longitudinal shear capacity of profiled composite slab (PCS). The shear value estimations from these two methods shows conflicting values with a very high difference (26%), and this constitutes a s...
