Abstract The behavior of isolated reinforced concrete (RC) footings is strongly influenced by the interaction between the footing and supporting soil, which governs settlement, load capacity, and contact stress distribution. Classical analytical solutions often overestimate edge stresses and fail to account for soil nonlinearity, progressive footing cracking, and stiffness degradation.

Abstract The performance and design of reinforced concrete, also known as slender beams are explained in the current study by a number of international codes. Slender beams are essential in modern construction because they preserve structural integrity while allowing for efficient material use.

Abstract Post-installing steel bars—or anchors—using chemical agents is nowadays instrumental in repairing and strengthening existing concrete structures. In this experimental research project, beside three cast-in-place specimens provided with ordinary ribbed bars (reference specimens), eighteen specimens were designed and cast to investigate bond performance of chemically-bonded steel bars placed inside concrete blocks, subjected to a pull-out load.
