Structural Concrete, EarlyView.Abstract The reinforcement corrosion is one of the main degradation mechanisms in reinforced concrete structures. Its effects can harm structural elements by reducing mechanical capacity, mainly due to diminished reinforcement properties and expansive reactions within the concrete.

Experimental Study of a Novel Type Joint Used in Precast Reinforced Concrete Frame Under Reversals
Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Prefabricated components are an integral part of the prefabricated construction. One of the main challenges in seismic regions is developing constructible connections between prefabricated components that can withstand inelastic cyclic deformations. This study introduces a novel type of joint designed to connect prefabricated concrete columns and beams

ce/papers, Volume 8, Issue 6, Page 993-998, December 2025.Abstract This study presents an in‐depth investigation of a cold‐formed steel portal frame structure, originally designed in the 1950s, through advanced nonlinear analysis. The research aims to compare traditional structural modelling approaches with more detailed nonlinear modelling techniques while evaluating various retrofitting strategies.
