Effect of soil subgrade modulus on raft foundation behavior

Behavior of Piled Raft Foundation on Heterogeneous Clay Deposits Using Random Field Theory

In the case of problematic soils and tall buildings where the design requirements cannot be satisfied merely by a raft foundation, it is of common practice to improve the raft performance by adding a number of piles so that the ultimate load capacity and settlement behavior can be enhanced. In this study, the effect of spatial variability of soil parameters on the bearing capacity of piled raft...

Effect of Pile Foundation on Natural Frequency of Soil Layer

Free vibration of soil often occurs during earthquakes. Since the vibration caused by earthquake does not have (steady state harmonic vibration) continuity, the alluvium vibrates with its natural frequency between two natural seismic waves. This study evaluates the effect of piles on the period of free vibration of a soil layer using numerical method. In the first stage, using analytical equati...

Spatial Correlation of Mechanical Properties of subgrade Soil for Foundation Characterization

Response of Raft Foundation on Varying Stratum

The effect on raft foundation of a barrage due to varying stratum has been examined using finite element analysis. The raft foundation is completely resting on soil media and surrounded by soil and rock media. Eight noded brick elements have been used for three-dimensional modeling and meshing of the rock, soil, cut-off, pier, beam and abutment but raft foundation has been meshed using plate el...

effect of oral presentation on development of l2 learners grammar

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
