Computation of Core Floor Slabs of Different Length

Abstract

Abstract The purpose of this research is to study what the crosscurrent representation format of core slabs is for samples of different length, by investigating the effect of the above factors on the load-bearing and stress-related properties, as well as the cracking load. The authors examined samples of slabs of different length, freestanding and working in bending, with a cross-section in a natural form, in comparison with samples of similar length in an I-beam shape. The samples were systematically loaded an interval of one kN until the yield point of reinforcement in the tension area was reached. The authors completed a numerical study of core slabs in a nonlinear setting. The researchers designed load-deflection plots when modeling the corresponding lengths of samples with a natural and I-beam form of section. The scholars received and compared results with loading of the cracked condition, midspan deflections with a rupturing load. They found out that the length of the slab affects the calculation results of the shapes issued: the shorter the length, the more highlighted deviation in the load-deflection plots. The authors suggested correction coefficients to perform a refined calculation of slabs for cracking, deflection, and rupturing loads.
