Effects of Reinforcing Elements in Soil Reinforcement
Abstract: The inclusion of reinforcing elements in a soil mass improves its geotechnical properties. The principle behind soil reinforcement is that the reinforcing elements absorb the tensile load and shear stress within the reinforced structures and hence prevent the shear failure and settlement. The friction developed between the interface of soil and reinforcing element improves the properties of soil. Different types of natural and synthetic fibers have been used in various …

Rural Building Base Isolation for Seismic Protection Using LRB and Friction Isolator
Abstract: Over 50% of the population of India, which is still developing, lives in unreinforced masonry buildings. Masonry constructions perform poorly and can collapse suddenly because they are susceptible to seismic loads and loads acting out of plane. Building collapse not only destroys public property but also claims life. It has been demonstrated that base isolation approaches for these types of structures are advantageous; in the event of seismic forces, they …
