چکیده
Experimental work was carried out to investigate the effect of fire flame (high temperature) on specimens one way slabs using Self Compacted Concrete (SCC). By furnace manufactured for this purpose, twenty reinforced concrete slab were exposed direct flame. All have same dimensions. The cooled in two types, gradually by left them air and suddenly water. After that tested under point loads, study, different: temperature levels (300ºC, 500ºC 700ºC), cooling rate (gradually sudden conditions) compressive strength, modulus rupture, flexural strength behavior comparing results with without burning (reference specimens). showed that, rupture decreases while maximum (central) deflection increases increasing temperature. For residual is less than greater. 20 MPa cooled, bending percent 81.5%, 75% 62.3% ,while increase central 5%, 33%, 105% at 300ºC, 700ºC respectively. temperatures above 77.9%, 68.3% 58.3% 25%, 52%, 118% When increase, experiences small lower 300 ºC 500 burn decrease significant 700

MOUTH BROODING FISH ALGORITHM FOR COST OPTIMIZATION OF REINFORCED CONCRETE ONE-WAY RIBBED SLABS
In this paper, the optimum design of a reinforced concrete one-way ribbed slab, is presented via recently developed metaheuristic algorithm, namely, the Mouth Brooding Fish (MBF). Meta-heuristics based on evolutionary computation and swarm intelligence are outstanding examples of nature-inspired solution techniques. The MBF algorithm simulates the symbiotic interaction strategies adopted by org...

In this paper, a new robust metaheuristic optimization algorithm called improved time evolutionary optimization (ITEO) is applied to design reinforced concrete one-way ribbed slabs. Geometric and strength characteristics of concrete slabs are considered as design variables. The optimal design is such that in addition to achieving the minimum cost, all design constraints are satisfied under Amer...
