This paper presents a Cuckoo Optimization Algorithm (COA) model for the cost optimization of the one-way and two-way reinforced concrete (RC) slabs according to ACI code. The objective function is the total cost of the slabs including the cost of the concrete and that of the reinforcing steel. In this paper, One-way and two-way slabs with various end conditions are formulated as ACI code. The t...

High Si concentrations in third-generation advanced high-strength steels (AHSS) are known to cause cracking continuous cast slabs during cooling at temperatures below 300 °C. To investigate the mechanism connecting this embrittlement, impact toughness tests conducted on as-cast Fe–0.2C–3.0Mn with 0.5, 1.5, and 3.0 wt% between 100 400 The propagation path of cracks through microstructure specime...
