In this paper, optimum design of three-dimensional (3D) multi-story reinforced concrete (RC) structures is obtained using an improved version the plasma generation optimization (IPGO) algorithm. The reinforcing bars and geometry cross-sections are considered as discrete variables that chosen from a prearranged section database. objective function cost framework, steel concrete. moment shear fra...

Existing physics-based modeling approaches do not have a good compromise between performance and computational efficiency in predicting the seismic response of reinforced concrete (RC) frames, where high-fidelity models (e.g., fiber-based method) reasonable predictive but are computationally demanding, while more simplified shear building model) opposite. This paper proposes novel artificial in...

Cracking of the concrete cover due to corrosion is defined as the serviceability limit state of reinforced concrete structures. This study evaluated the influence of a mineral admixture i.e. nano wollastonite on corrosion performance and serviceability of reinforced concrete structures by performing an accelerated corrosion test on ten reinforced concrete beams under a sustained load. To do so,...

Reinforced Concrete (RC) buildings with masonry infills are a very common structural typology worldwide for civil, strategic, or productive use. Damage to may cause danger human lives and strongly affects economic losses, as shown during past earthquakes. In the current literature, different approaches available modeling in-plane response of infilled frames constitutive laws generally calibrate...
