SHAKING TABLE TESTS ON NARROW MECHANICALLY STABILIZED EARTH WALLS

08319 - Long Term Corrosion Performance of Soil Reinforcement in Mechanically Stabilized Earth Walls

Mechanically stabilized earth walls, MSEW, around Florida were instrumented through their concrete covers to survey corrosion rates of galvanized strip soil reinforcement by polarization measurements. The first broad survey was made 10 years ago as a baseline and a new survey is currently underway to assess long term corrosion rate trends. Initial results of an ongoing survey confirm low rates ...

Runway Extension With a Vegetated mechanically Stabilized Earth Wall (VMSEW)

Finite Element Analysis of Earth Pressures for Narrow Retaining Walls

High traffic demands have led to widening of existing highways to accommodate increased traffic volume. However, due to the high cost of additional right-of-way and limited space available at job sites, construction of earth retaining walls is often done under a constrained space. This leads to retaining walls that are narrower than in design guidelines. This type of walls is referred as “Narro...

THE SHAKING TABLE CONCENTRATOR: INFLUENCE OF TABLE PARAMETERS ON MANGANESE CONCENTRATION

Abstract: point of view. In this study, a shaking-table was used for concentrating a manganese ore sample from the Ghasem Abadarea in Kerman, Iran. Experiments were designed by using LThe influence of each variable and their interactions on the operation of the device was studied. The variables underinvestigation were: table slope, table frequency, water flowrate, feed rate, and particle size. ...

On the Optimum Placement of Dissipators in a Steel Model Building Subjected to Shaking-Table Tests

The following research presents the numerical and experimental results obtained on a reduced scale steel model of a medium-rise building structure dynamically protected with energy dissipaters. The steel-steel friction dissipates energy as the structure undergoes interstory drifts. A preliminary numerical analysis is performed to determine the best position of the friction dampers in the longit...
