In order to obtain the study of bonding properties between reinforcement-concrete and give full play material properties, a lot research has been carried out on reinforcement-concrete. Existing studies contain mainly bonds, reinforcement lap, anchorage reinforcement. The bond test measures bond-slip curve two determine strength concrete. lap is used for performance length in concrete, whether b...

in this paper, the effect of cyclic loading on punching strength of flat slabs strengthened with carbon fiber reinforced polymer (cfrp) sheets is studied. experimental results of ten slab specimens under monotonic and cyclic loading are analyzed. eight specimens were strengthened with cfrp sheets on the tensile face of the slabs and the two other specimens were kept un-strengthened as control s...

The use of fiber reinforced polymers (FRP) for reinforcement of aging and deteriorating concrete members has emerged as a viable and cost effective alternative to traditional repair and strengthening techniques to upgrade deficient structures to meet today’s design standards (Crasto et al., 1996; Myers et al., 2000). The load carrying ability of structures such as beams and columns can be enhan...

The current study investigates the capacity of proposed meta-material layout for blast protection above-ground steel pipes against explosions. philosophy layout’s design is described adequately, and 1D periodic structures’ theory adopted analytical prediction band-gaps. special characteristics loading are explained, specific time-related parameters calculated. tested numerically nine explosion ...

Given the increasing age of our built environment, including concrete structures, stakeholders in construction industry require innovative and effective strengthening methods. In several studies onsite applications, iron-based shape memory alloy (Fe-SMA) reinforcements have proven to be competitive alternatives well-established materials. The objective this investigation was study effectiveness...

Composite steel girders with concrete have been used for many years and advances in structural fabrication technology established their optimization. One of the changes I-beams during past few has availability web corrugation. The economic design normally requires thin webs. Moreover, using externally prestressed tendons as a strengthening technique controls deflections stresses. However, this ...
