The corrosion of rebar is one the main problem in construction industry. A lot amount spent on repair work every year but none them that effective. Therefore, recent studies are being conducting FRP due to brittle nature and bonding performance. We have also used PVA fiber concrete increase strength concrete. we using Hybrid beams which replaced corner with BFRP bars because their superior effe...

This paper describes the development of new air-coupled ultrawideband ground-penetrating radar (GPR) for highway pavement and bridge deck inspections that can achieve high spatial resolution and high inspection performance while operating on vehicles driving at regular highway speeds. Themajor design features include dual-frequency band operation, 8 gigasamples per second high-speed real-time d...

Steel formworks are widely used in prefabricated buildings thanks to their good characteristics. With the rapid development of engineering construction China, steel formwork concrete structures, characterized by convenient construction, seismic performance, and high strength, expected be more extensively applied practice. However, bearing capacity different forms is still unclear. Two columns w...

Rebar engineering in the construction industry lacks effective technical means and has a high processing cost waste rate. Under background of intelligent construction, centralized mode steel bars prefabricated factories realizes automatic improves efficiency bars. Using C# programming language, combined with Revit secondary development technology, generation rebar model export drawing are reali...

Abstract Recently, new materials and methods have been implemented to improve the performance of reinforced concrete columns. This paper studies experimentally behavior high-strength columns, with additional internal confinement using hexagonal chicken wire mesh (HCWM) enhance ductility, energy absorption, ultimate strength reduce brittleness traditional Eight double-ended one-third-scale colum...

Cross-laminated bamboo (CLB) have a high strength to weight ratio and stable bidirectional mechanical properties. Inspired by the investigation on cross-laminated timber (CLT) rocking walls, CLB walls with conventional friction dampers (CFDs) are studied in this paper. To investigate properties of wall, seven tests conducted under cyclic loading scheme, different test parameters, including exis...

Abstract Since the nineteenth century, reinforced concrete was evolved as a crucial material for construction. This popular composite is broadly used in different building typologies. However, decaying of steel rebar due to corrosion identified hindrance that can affect quality structures. In reference this, glass fiber-reinforced polymer (GFRP) bar essential because corrosion-resistant propert...

While various approaches have been developed to minimize rebar cutting waste, such as optimizing patterns and the lap splice position, reducing usage by minimizing number of splices remains uninvestigated. In response these issues, a two-stage optimization algorithm was that prioritizes use special-length achieve near-zero waste (N0RCW) less than 1%, while also overall usage. The first optimize...

ID No : 43 ABSTRACT Concrete tends to crack due to its relatively low tensile strength which jeopardizes the good condition of steel reinforcement bars. Concrete cracks start at micro level and facilitate ingression of corrosive substances such as SO4 , Cl, O2. Corrosion of the rebar may result in failure of the structure. Self-healing concrete can provide crack repair immediately after crack i...

Improved autogenous healing capacity of concrete using superabsorbent polymers (SAPs) was used as an efficient approach for mitigating damage between steel rebar and self-consolidating (SCC). The results normal (NC) those SCC mixtures were compared. Two SAPs with different particle sizes chemical compositions in the experimental program. Results showed that despite greater reduction effect SAP ...
