<p>Although numerous studies have been conducted, a recommended practice for incorporation of earthquake loading into the geotechnical design considerations for subsea structures such as wells, manifolds, and PLETs, and pipelines is not consistent. Industry ...

Following the magnitude 7.1 Greendale earthquake on 4 September, 2010 and the magnitude 6.3 Lyttelton aftershock on 22 February, 2011 (which caused severe damage to the Christchurch CBD, the Eastern and Southern suburbs, the Port Hills and Lyttelton), the ...

A seismic improvement works were completed on Market Road Underpass (MRU) in Auckland. The bridge consists of three structures: The Underpass, the Motorway Off-ramp and the Rail Overbridge. In the NZTA’s "Seismic Screening" of all state highway bridges MRU ...

A future earthquake in the city of Wellington will cause widespread building and infrastructure damage, particularly on soft soils. It is also anticipated that all major transport routes (air, sea, rail and road) out of the region and many within the region ...

A series of full scale tests have been undertaken to assess the performance of ground strengthening methods to improve seismic performance of liquefiable soils in the Christchurch area. The tests used sequences of explosive charges to simulate seismic shaking ...

The seismic design criteria applied to siting commercial nuclear power plants operating in the United States received increased attention following the March 11, 2011, earthquake and tsunami that devastated Japan’s Fukushima Daiichi nuclear power station. ...

Spectra and peak ground accelerations for the assessment and rebuilding of structures in Christchurch were revised rapidly following the magnitude 6.2 earthquake on 22 February 2011. The NZS1170.5:2004 hazard factor Z for Christchurch was quickly raised from ...

All buildings are subjected to some degree of torsion which in turn changes the member demands from that of translation only. Torsional effects on buildings subjected to earthquakes are not found directly in structural analysis unless full three-dimensional ...

This chapter is a guide to the geotechnical designer who is responsible for providing geotechnical/seismicinput parameters to the structural engineers for their use in structural design of the transportation infrastructure (e.g., bridges, retaining walls, ...

<p>This manual is intended to provide a technical resource for bridge and geotechnical engineers responsible for seismic analysis and design of transportation geotechnical features and structures such as soil and rock slopes, earth embankments, retaining structures ...
