Modelling of exterior RC beam-column joints for the seismic assessment of RC-frames
, 2022 Past and recent seismic events underlined unexpected damage mechanisms of RC-frames consisting of widespread damages and collapses of beam-column joints. These outcomes, mainly concerned RC-frames designed before the introduction of modern seismic codes,

Comparison of Dynamic Characteristics of Prestressed and Reinforced Concrete Beams
Düzce Üniversitesi Bilim ve Teknoloji Dergisi, 2019 To determine the dynamic characteristics of bridges built with prestressed and reinforced concrete beams, thedynamic properties of such beams should be known. Prestressing force is applied to the prestressed concrete (PSC)beam, unlike reinforced concrete

Proceedings of International Structural Engineering and Construction, 2016 Twelve prototype rectangular RC beams (120 x 150 x 1000 mm) were constructed and evaluated using flexural test to investigate the employment of advanced composites in repairing corroded reinforced concrete (RC) beams. Three concrete mixtures with effective w/c ratio of 0.4 and cement content of 370 kg/m3 were utilized in the study: control ordinary ...
