Geogrid Mechanical Damage Caused by Recycled Construction and Demolition Waste (RCDW): Influence of Grain Size Distribution

April 06, 2020
Recent studies have shown that recycled construction and demolition waste (RCDW) can be used as backfill material in geosynthetics reinforced soil (GRS) structures. However, besides the environmental and economic benefits of this practice, it is necessary to evaluate the mechanical damages that RCDW could cause to the reinforcement elements. This study aims to i...

Numerical Investigations on Seismic Bearing Capacity of Interfering Strip Footings

April 30, 2020
The interaction between footings placed at close proximity affects the ultimate bearing capacity, settlement, and tilt of adjacent footings, especially under seismic loading. This paper reports the numerical finite element analysis to investigate the interference effect on the seismic bearing capacity of closely spaced rigid strip footings for a wide range of fo...

Drained and Undrained Behavior of an Aeolian Sand from Natal, Brazil

March 11, 2020

The behavior of sands subjected to diverse loading conditions has been the object of many studies in recent decades. Constitutive models that are able to simulate the behavior of sands have been developed based on critical state theory. Researchers have shown that the defining parameters of the critical state line (CSL) can be obtained by performing dra...

Effects of Hydraulic Gradient Variation on the Structure and Strength of a Compacted Tropical Soil

May 26, 2020
Tropical soils have been extensively studied to evaluate the technical feasibility of their application in hydraulic earthworks such as compacted clay barriers in landfills. In these earthworks, the water flow in the porous medium generates percolation forces that can promote structural changes in the soil, with possible deleterious repercussions on its mechanic...
