The aging of reinforced concrete structures is one the biggest concerns in civil engineering today since billions dollars are spent annually on deck repairs and replacements. This study focuses rehabilitation box girders used bridge construction. Bridge with a new overlay possesses many challenges that involve cracking debonding caused by restraining effect substrate. leads to development tensi...

Fire has significant effects on the residual resistance of steel structures. It is necessary to accurately clarify its Q690 HSS plate girders, which have been widely used. In this paper, ultimate and effective service girders after a fire are obtained using material tests finite element (FE) analysis including parametric studies, where data 210 models were collected. The four key parameters (hw...

In this paper, the shear strength of corrugated web girders made EN 1.4162/LDX 2101 stainless steel is investigated. Four full-scale trapezoidal were tested under shear. Before conducting tests, DIC was used to measure real geometric imperfections in panels. Complementary finite element analysis studies conducted assess sensitivity initial imperfections. The experimental results indicated that ...
