Behaviour of Soft Clayey Soil Improved by Fly Ash and Geogrid under Cyclic Loading

a study of multilayer soil-fly ash layered system under cyclic loading

in the present investigation, the cyclic load deformation behaviour of soil-fly ash layered system isstudied using different intensities of failure load (i = 25%, 50% and 75%) with varying number of cycles (n =10, 50 and 100). an attempt has been made to establish the use of fly ash as a fill material for embankments ofhighways and railways and to examine the effect of cyclic loading on the lay...

Effect of Geogrid Aperture Size and Soil Particle Size on Geogrid-Soil Interaction under Pull-Out Loading

Soil-Structure Interaction of Buried Pipes Under Cyclic Loading Conditions

The safety of lifelines, as the most important urban facilities, under different conditions highly depends on the safe design and performance of these buried structures. This cannot be achieved unless their actual behaviors are well understood and considered at the designing stage. A new physical model was developed in Amirkabir University of Technology to study the behavior of buried pipes und...

Behaviour of Reinforced Fibrous Concrete Beams under Reversed Cyclic Loading

When earthquakes occur, energy released by the earthquake gets induced into the structure as ground motion and this energy has to be dissipated for safety reasons. To release seismic energy, the structure should damage in such a way that on one hand, collapse of structure should not occur and on the other hand, after the earthquake, damage should be economically feasible to repair. To avoid the...

Behaviour of poorly detailed lap-splices under cyclic loading

This paper presents the first part of a series of uniaxial cyclic tests on lap-splices. The work is conducted within the framework of a project on the seismic behaviour of existing, poorly detailed bridge piers which are typically constructed with a lap-splice above the footing. The test series presented here was initiated to study the influence of load history, especially with regards to the c...
