The design of Municipal Solid Waste (MSW) landfills requires the selection of representative MSW material properties. The profession’s understanding of the mechanical response of MSW has evolved significantly in recent years, but many aspects of the response of MSW remain uncertain. A research project involving five organizations was conducted to systematically evaluate the factors that affect ...

experimental tests were performed to study the seismic behavior and performance ofmodified steel chevron braced frame systems, which incorporate a vertical slotted connection(vsc) detail between the top of the braces and the floor beam above. the vsc detail isintended to prevent vertical load transfer to the beam and limit brace forces to thecompressive resistance of the members. full-scale qua...

Triaxial compression and extension tests have been conducted under different initial anisotropy conditions to investigate the undrained response of a crushed silica sand. The loose medium specimens were prepared using moist tamping method. Five stress paths with ratios (q/p?) employed prepare anisotropically consolidated specimens. Several specific condition in which rotation occurred monotonic...

A comprehensive experimental study that quantifies the influence of coupled compression and shear wave loading on liquefaction susceptibility sands is presented. Such typical in situ, leads to complex principal stress rotation, which turn impacts potential for soils even if cyclic intensity remains constant. The nature degree rotation caused by this are significantly influenced initial consolid...

abstract: this paper presents the results of pullout tests on uniaxial geogrid embedded in silica sand under monotonic and cyclic pullout forces. the new testing device as a recently developed automated pullout test device for soil-geogrid strength and deformation behavior investigation is capable of applying load/displacement controlled monotonic/cyclic forces at different rates/frequencies an...

[1] Understanding the mechanical behavior of rock is critical for researchers and decision-makers in fields from petroleum recovery to hazardous waste disposal. Traditional continuum-based numerical models are hampered by inadequate constitutive relationships governing fracture initiation and growth. To overcome limits associated with continuum models we employed a discrete model based on the f...

As society moves towards decarbonisation, it is important to assess the hydromechanical behaviour of binders that could offer a low-carbon alternative Portland cement in ground improvement technologies. This work considers two such alternatives: one still largely unexplored (metakaolin-based geopolymers) and better known (colloidal silica). Results from unconfined compressive strength, permeabi...

Offshore wind power, as an efficient renewable energy source, is being vigorously developed nowadays. However, the liquefaction of marine sand due to earthquakes brings potential safety hazards turbine structures. In this study, a series resonant column and undrained cyclic triaxial tests were carried out investigate stiffness degradation characteristics in offshore farm at East Nan-ao area Gua...

This research investigates the static and cyclic characteristics of recycled glass (RG) as a supplementary material with concrete aggregate (RCA) in rail track capping layer. RG was blended by-weight RCA 10% increments up to 50% content. A performance-based laboratory testing scheme designed according field loading conditions layers tracks. Basic geotechnical properties + blends were evaluated ...
