<p>The first Metro Project in Indonesia has commenced finally and half of the packages are underground structure. The civil packages have been achieving some significant progress in construction where the majority of underground stations are under construction ...

<p>The paper reviews literature and codes related to performance-based seismic design (PBSD) of reinforced concrete building. Performance objectives such as immediate occupancy, collapse prevention, or life-safety are used to define the state (condition) ...

<p>The engineering understanding of the behaviour shallow foundation in earthquakes has developed piecemeal over the past sixty years with the emergence and refinement of solutions to several separate aspects of the overall problem, prompted and provoked by ...

<p>The response of surface foundations to large overturning moments is studied under undrained conditions. Rigid circular, strip, and rectangular footings of various aspect ratios are considered, with the soil modeled as an inelastic homogeneous deposit, characterized ...

At 12:51pm local time on 22 February 2011, a Mw 6.2 aftershock of the September 4, 2010, Darfield Earthquake shook the city of Christchurch, New Zealand. The aftershock occurred on an unmapped fault less than 8 km from the city center resulting in the collapse ...

Shortcomings of modern seismic design in reinforced concrete have necessitated the development of new systems capable of addressing these issues. Able to be constructed using existing industry techniques, the slotted beam is one such practicable, economic ...

The Waikato Expressway is being constructed in a number of sections. Opus has been involved in the scheme assessment and specimen design stages for the Hamilton and Cambridge Bypass sections and is currently part of the alliance team constructing the Te Rapa ...

<p>Most of the Egyptian irrigation structures were built many decades ago. Most of these structures may be classified as unsafe structures when making an assessment of their resistance to earthquake loads in accordance with the current specifications. This ...

Earthquakes subject tunnel linings to transient strains due to ground shaking, and can cause localized permanent strains in zones of fault rupture. These issues are discussed with respect to seismic analyses and design strategies. Most underground structures ...

<p>A performance-based methodology for seismic analysis and design of the geosynthetic elements of waste containment systems, including landfills and heap leach pads, has been developed. The methodology offers a rational alternative to the current state of ...
