This study aims at researching damage mechanism of tunnel portal and front slope caused by seismic excitation, while post-earthquake field investigations and shaking table tests were conducted. Seismic damage mechanism can be drawn from comparison between ...

The Nelson Marlborough Institute of Technology Arts building is the world’s first commercial implementation of a post tensioned Laminated Veneer Lumber (LVL) shear wall system based on EXPAN technology. In order to understand the response of the building in ...

This paper presents a study of the dynamic analysis of a building before and after devastating earthquakes using system identification. The eight storey reinforced concrete building is instrumented with 10 accelerometers. The time domain N4SID system identification ...

This paper presents a parametric investigation of the seismic response of circular tunnel. The dynamic response in non-linear conditions due to seismic shaking is analysed numerically making use of the finite element program ICFEP in non-linear conditions. ...

This research develops a first‐order estimate of the large strain dynamic response of peaty organic soils, with the goal of improving system reliability estimates of the Bay Delta levee network.

This research involves shake table testing of 1g scale models that mimic the coupled seismic response of a structure on a shallow mat foundation and the foundation soil (termed soil-foundation-structure-interaction or SFSI).

In order to understand the structural behavior, it is useful to study the effects of soil-structure interaction. But usually soil-structure interaction studies are done with the assumption that foundation is fixed to the soil. During strong earthquake motions, ...

Cyclic1D is a nonlinear Finite Element program for one-dimensional (1D) lateral dynamic site-response simulations. The program operates in the time domain, allowing for linear (Hughes 1987) and nonlinear studies. Nonlinearity is simulated by incremental ...

The present study concerns analysis of the seismic response of earth dams. The behaviour of both the shell and core of the dam is described using the simple and popular non associated Mohr-Coulomb criterion. The use of this constitutive model is justified ...

The effects of near-fault vertical accelerations on the overall response of ordinary highway bridges are investigated. Nonlinear simulation models with varying configurations of an existing bridge in California are considered in the analytical study. A comprehensive ...
