...Yan Yao; Huang Tang; Jianxin Peng; Shuhao Yao; Zonggui Yang; Jiani Yu Flexural tests of locally corroded prestressed concrete beams (PCBs) were carried out to study their displacement behaviour. A finite-element model of the locally corroded PCBs was then established, and the influences of concrete...

...-surface-mounted (NSM) steel bars and confined with stainless steel (SS) strips as externally bonded reinforcement (EBR) in an attempt to enhance their vertical load-bearing capacity. A series of tests was carried out to study the effects of the presence of openings, strengthening technique (NSM...

.... A novel flexural strengthening technique for normal concrete circular beams (NCCBs) is proposed, using engineered cementitious composites (ECCs) and stainless steel tubes (SSTs). To examine the application of the proposed strengthening method, five NCCBs were fabricated and tested under static loading...

... shear contribution shear failure shear span-to-depth ratio shear strength size effect structural analysis testing Research on reinforced concrete (RC) structures is primarily focused on the bending failure of the reinforcement, with limited attention given to the shear capacity...

... performances, safety margins and limitations of the connections, experimental investigations are essential. Experimental results from laboratory tests on a large-scale prototype model of an original roof beam–column connection show its actual bearing capacity, damage propagation pattern and specific failure...

...Xin Ge; Yanbin Tan; Sen Du; Yongjiang Xie; Yongjie Zheng; Linxiang Li; Lu Yang Existing methods for evaluating the resistance of concrete to freeze–thaw cycles might not be suitable for concrete used in ballastless track structures (BTSs). In this study a new test method was designed to investigate...
