Strategies for faster infrastructure development with Geosynthetics

Venkatappa, Rao G. (Indian journals, 2017-02)

Geosynthetics are planar, polymeric (synthetic or natural) materials used in contact with soil/rock and/or any other geotechnical material, for serving functions of Filtration, Drainage, Separation, Reinforcement, Protection, ...
Geosynthetic reinforced soil Structures-A critical appraisal of design and construction

Venkatappa, Rao G. (Indian journals, 2017-02)

The awareness of geosynthetics in the country has begun around the year 1985. Soon after, the first Geosynthetic Reinforced Soil Retaining Wall has been built. Since then many hundreds of such structures have been constructed ...
Effect of fire on in-plane and out-of-plane behavior of reinforced concrete frames with and without masonry infills

Kumar, Puneet; Srivastava, Gaurav (Elsevier, 2018-04)

The present study develops a generic three-dimensional (3D) finite element (FE) model to characterize the in-plane and out-of-plane behavior of masonry infill reinforced concrete (RC) frames under fire exposure. The developed ...
Stress-state dependency of small-strain shear modulus in silty sand and sandy silt of Ganga

Prashant, Amit; Bhattacharya, Debayan; Gundlapalli, S. (Thomas Telford, 2018-02)

This study explores the effect of stress state on small strain modulus (Gmax) in the naturally occurring Ganga sand and silt using bender elements during a series of carefully performed undrained triaxial tests. Unlike the ...
Coherency model for translational and rotational ground motions

Rodda, Gopala Krishna; Basu, Dhiman (Springer, 2018-07)

Spatial variability of the translational ground motion may influence the seismic design of certain civil engineering structures with spatially extended foundations. Lagged coherency is usually considered to be the best ...
Variation of collapse potential and stiffness degradation with matric suction of compacted unsaturated cohesive soil

Pandya, Saloni; Sachan, Ajanta (Taylor & Francis, 2017-11)

Collapse of soil skeleton due to variation in its loading and boundary conditions impacts the strength and stability of soil in its unsaturated state. The present study is focused on the influence of matric suction on ...
Effect of crushing and strain rate on mechanical behavior of type-F fly ash

Gupta, Kanika; Sachan, Ajanta (Springer Verlag, 2018-03)

Fly ash is a by-product of coal combustion from thermal power plant. It comprises of hollow spherical silt size particles with low specific gravity. The increased use of fly ash in highway/railway embankment construction ...
Seismic vulnerability assessment of f low-rise reinforced concrete buildings affected by the 2015 Gorkha, Nepal Earthquake

Brzev, Svetlana; Pandey, Bishnu; Maharjan, Dev Kumar; Ventura, Carlos (Earthquake Engineering Research Institute, 2017-11)

Low-rise reinforced concrete (RC) frames with brick masonry infill walls up to five stories high have been used for housing construction in Nepal since the late 1980s. Many buildings of this type were damaged and/or collapsed ...
Effect of in-plane boundary conditions on elastic buckling behavior of solid and perforated plates

Prajapat, Kanta; Ray-Chaudhuri, Samit; Kumar, Ashwini (Elsevier, 2015-05)

In this work, finite element method is used to obtain elastic buckling loads and mode shapes of plates. The effect of four different in-plane boundary conditions on the elastic buckling load of simply supported plates ...
Dominant control of agriculture and irrigation on urban heat island in India

Kumar, Rahul; Mishra, Vimal; Buzan, Jonathan R.; Kumar, Rohini; Shindell, Huber; Matthew, Drew (Nature Publishing Group, 2017-10)

As is true in many regions, India experiences surface Urban Heat Island (UHI) effect that is well understood, but the causes of the more recently discovered Urban Cool Island (UCI) effect remain poorly constrained. This ...
Nonlinear analysis of reinforced concrete plane frames exposed to fire using direct stiffness method

Prakash, P. Ravi; Srivastava, Gaurav (SAGE Publications, 2017-10)
