Concrete structures provided with steel bars may undergo deterioration due to fatigue and corrosion, which leads an increase in repair maintenance costs. An innovative approach eliminating these drawbacks lies the utilisation of glass-fibre-reinforced polymer (GFRP) sheets as reinforcement concrete instead bars. This article relates investigation flexural behaviour ordinary portland cement (OPC...

Unbonded post-tensioned (UPT) flat plate concrete slabs are popular for modern continuous multiple bay floor assemblies due to economic and sustainability benefits (reductions in slab thickness and building selfweight) and structural advantages (decreased deflections over larger spans). Only limited research has been conducted on the performance of UPT flat plate slabs under fire conditions, ye...

Order to investigate the failure effect of textile reinforced concrete (TRC) plate under bending load, corresponding finite element model is established. By comparing numerical simulation results with experimental results, rationality and feasibility are verified, then crack extension TRC ultimate strain carbon analyzed. The mode slab load obtained, it found that has better reinforcement effect...

At two trench segments below the Andes, the Nazca Plate is subducting sub-horizontally over ∼200-300 km, thought to result from a combination of buoyant oceanic-plateau subduction and hydrodynamic mantle-wedge suction. Whether the actual conditions for both processes to work in concert existed is uncertain. Here we infer from a tectonic reconstruction of the Andes constructed in a mantle refere...

ABSTRUCT: Recently, in the attention in response to global warming issues and sustainable society, the manufacturing using natural materials has become actively. Bamboo, low cost, fast growing, and broad distribution of growth, is expected to contribute significantly to earthquake-resistant construction and seismic retrofit technology in the developing countries. The authors also have been stud...
