Since the structure and foundation are built on soil, the soil is the major platform by which seismic vibrations are transmitted to the structure, and has noticeable effects on the response and behavior of structure during earthquakes. In this research, the recently introduced Performance-based plastic design (PBPD) and its modified Performance-based plastic design (MPBPD) method in which soil ...

The spatial variation of soil properties with specific reference to their coefficient (COV), and effect on deep foundation designs, is discussed. difficulties in developing strength factors (Φ) for lateral load response governed by multiple resistance variables are examined. Classical current analytical experimental state the art described. Influence amended topsoils shear cohesion also Finally...

In most of the designs of rigid structural frames, the analysis is carried out by assuming fixity at base, which means that the building is idealized to rest on hard rock. This paper discusses the importance of considering the effect of soil stiffness on the seismic performance of rigid structural frame system resting on it. Flexibility of soil causes lengthening of lateral natural period of th...

In Bhopal, the widespread occurrences of cracking due to alternate swelling and shrinking in lightly loaded structures provided with traditional foundation like the strip footings in are covered by swelling soil. It is likely that foundation movements, due to shrinkage and swelling of expansive soil as a result of moisture content changes are responsible for more damage to building than any oth...

To study the effects of spudcan penetration on the adjacent foundations of offshore platforms, experiments and numerical simulations (using business software ABAQUS) are carried out. It is shown that the penetration of spudcan can cause the soil layer affected in an annular zone. The affected zone has a maximum width of one times the diameter of the spudcan. The deflection of the platform’s fou...
