<p>This paper discusses some aspects of the seismic behaviour of large homogeneous earth dams. Numerical analyses were carried out using a plane-strain finite difference model of an existing dam that has been calibrated using the monitoring data taken during ...

<p>We propose a new simplified method for assessing the seismic performance of homogeneous small earth dams (height&le;20 m) founded on bedrock. Dynamic decoupled calculations were performed on seven accelerograms applied to 33 structural and geotechnical ...

<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) ...

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 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 ...

This paper compares the historical and current approaches to building design in New Zealand with the performance based design approaches currently used in the United States under the framework of ASCE 41. Examples of building performance during the recent ...

<p>The purpose of this study is to clarify the seismic performance of piled raft foundations with ground improvement based on seismic observation records. The monitored building, which is a twelve-story base-isolated building, is located on loose silty sand ...

This document explains the underlying causes for the poor seismic performance of stone masonry buildings and offers techniques for improving it for both new and existing buildings. The proposed techniques have been proven in field applications, are relatively ...

<p>When an earthquake occurs, the surrounding soil and the structural elements can exhibit non-linear behaviour. In common practice, only non-linear behaviour of structural elements is evaluated. But, actually, the soil reaches the limit of its elastic behaviour ...

<p>On March 2005, the River Bureau of the Ministry of Land, Infrastructure and Transport issued &ldquo;Guidelines for Seismic Performance Evaluation of Dams during Large Earthquakes (Draft).&rdquo; The Draft Guidelines describe the methods for systematically ...
