Sustainability necessitates the protection of infrastructure from any kind deterioration over life cycle asset. Deterioration in capacity reinforced concrete (RC) (e.g., bridges, buildings, etc.) may result localised damage sustained during extreme loading scenarios, such as earthquakes, hurricanes or tsunamis. In addition, factors corrosion rebars ageing also deteriorate degrade an RC column, thereby necessitating immediate strengthening to either extend ensure its design is not limited....

Reinforced concrete (RC) impact-resistance barriers, such as rockfall often consist of a cantilever RC wall, which is expected to experience flexural bending under impact loading resist the associated design actions. In order investigate response behavior an large-scale experiment was carried out on fixed base cantilevered barrier wall measured 1.5 m in height, 3 length, and 0.23 thickness. Two torpedo shaped steel impactors with mass 280 435 kg were released from controlled heights ranging...

Code response spectrum models, which are used widely in the earthquake-resistant design of buildings, simple to apply but they do not necessarily represent real behavior an earthquake. A code model typically incorporates ground motion a diversity earthquake scenarios affecting site and does any specific scenario. The soil amplification phenomenon is also poorly represented, as current classification scheme contains little information over potential dynamic sediments. Site-specific spectra...

The seismic behavior of ductile high-strength RC (HSRC) columns that are constructed in regions high seismicity is well understood due to a number experimental studies conducted over the last few decades. However, limited HSRC commonly lower have received significantly less attention.

Columns in building frame systems are subjected to the combined action of bidirectional horizontal loading and axial load variation during an earthquake. Whilst behaviour RC columns under unidirectional lateral with constant is understood well, rarely studied, especially for limited ductile prevalent regions low moderate seismicity.

Precast concrete building cores are a widely used lateral load resisting system in low and mid-rise multi-storey buildings. However, despite their widespread use countries like Australia or New Zealand, very little research experimental testing has been undertaken to assess drift behaviour. This article will present the findings observations of recent programme into reinforced precast cores, which included three large-scale ‘box-shaped’ core specimens. Adjacent panels each specimen were...

Advanced forms of structural design (e.g. displacement-based methods) require knowledge the non-linear forcedisplacement behavior both overall building and individual lateral load resisting elements, i.e., walls or cores. Similarly, understanding behaviour elements in a structure can also allow for less conservative response to be calculated by better cracked (i.e., effective) properties various RC elements. Calculating an section typically involves using \'black box\' analysis packages,...
