Reliability of design of floor slab systems using plastic moment distribution method
(Altınbaş Üniversitesi, 2021) Sadek, Saif Mohamed; Çelik, Tuncer
This research study the reliability of design continuous floor slabs with varying end conditions under effected ultimate Loads by plastic theory. This paper has adopted approach using plastic moment distribution method in the design of solid slab. 16 rectangular slabs have same depth but different end conditions and dimension in x and y- directions were investigated. The results obtained from the continuous solid slabs by plastic moment distribution method achieved the conditions of equilibrium, mechanisms, and plastic moment and its was compared with computer program adopted elastic theory method under loading combination ultimate limit state and serviceability limit state. The results are compared according to the parameters of the British Code (BS 8810) allow that any value of bending moments by plastic method must be not less than 30 % of elastic moment at supports and at span (maximum sagging moments) in plastic are high in elastic analysis. After comparing, all the obtained results showed that they are in agreement with the determinants of the British code. The method adopted in this study gave the values of the plastic moment (MP), at which the plastic hinge (PH) is formed and true mechanism of failure.
