EFFECTS OF MULTIPLE DETONATIONS ON THE DAMAGE OF REINFORCED CONCRETE SLABS
reinforced concrete multiple detonation damage crater
2008/12/24
In this study, effects of multiple detonations on reinforced concrete (RC) slabs has been experimentally investigated to improve design and damage estimation methods of RC shelters. One of main resul...
SEISMIC RESPONSE OF UNDERGROUND REINFORCED CONCRETE STRUCTURE—CENTRIFUGE MODEL TEST AND ITS ANALYSIS
centrifuge model test underground structure seismic response numerical analysis
2008/12/22
A centrifuge model test with similitude of 1/20 is carried out to clarify the inelastic response character-istics of reinforced concrete members in the culvert type of underground structure. Numerica...
TWO-LEVEL SEISMIC DESIGN METHOD USING POST-YIELD STIFFNESS AND ITS APPLICATION TO UNBONDED BAR REINFORCED CONCRETE PIERS
post-yield stiffness two-level seismic design UBRC structure small section pier
2008/12/22
The two-level seismic design method using post-yield stiffness is proposed. The post-yield stifiness on the load —displacement relationship of the RC pier is found to be effective for the reduction o...

reduction factor ultimate flexural strength composite I-girder concrete crushing
2008/12/19
The ultimate flexural strength of composite steel girders with compact sections is examined through experimental investigation and elasto-plastic finite displacement analyses to develop a reduction f...
Effect of zinc phosphate chemical conversion coating on corrosion behaviour of mild steel in alkaline medium: protection of rebars in reinforced concrete
steel corrosion rebar protection alkaline medium phosphate coating hydroxyapatite
2010/10/12
We outline the ability of zinc phosphate coatings, obtained by chemical conversion, to protect
mild steel rebars against localized corrosion, generated by chloride ions in alkaline media. The corrosi...
Design of Reinforced Concrete Elements Under Fire
Concrete Reinforcement Fire Safety Temperature
2010/8/18
Fire safety regulations can have a major impact on many aspects of the overall design of a building, including layout, aesthetics, function, and cost. Rapid developments in modern building technology ...
Physical Model Method for Seismic Study of Concrete Dams
Concrete Dam Physical Model Earthquake Shaking table
2010/8/18
The study of the dynamic behaviour of concrete dams by means of the physical model method is very useful to understand the failure mechanism of these structures to action of the strong earthquakes. Ph...
Properties of Fiber Reinforced Polymer Concrete
Epoxy Resin Polymer Concrete Fiber Mechanical Strength
2010/8/18
Polymer concrete is a composite material realized with resin and aggregates. In the present study the epoxy resin was used for binding the aggregates. In the composition were introduced near the fly a...
