Abstract In this paper, a new methodology for time domain analysis of buildings on raft foundations considering soil – structure interaction is proposed. Sub-structuring technique used to separate the building as super-structure and underneath sub-structure. The can be modeled using any numerical method. However, in paper via BEM consider real area between column slabs. dynamic load considered ...

Seismic vulnerability assessment is crucial for evaluating the resilience of structures. OpenSees, an open-access and versatile tool, plays a pivotal role in accurately simulating complex behavior structures subjected to seismic loads. However, lacking built-in graphical user interface (GUI) one limitations OpenSees that can hinder usability accessibility. Moreover, users must rely on command-l...

Aseismic design of gravity wall still is a more difficult issue. The reason stems from the complexity of the problem which requires skills in soil mechanics, foundation engineering, soil-structure interaction along with knowledge of structure dynamics. Designing seismic gravity retaining structures deals with both kinematic interaction and inertial interaction but almost seismic building code n...

The effect of frequency content on the dynamic response of concrete gravity dams is investigated in this paper. Dams are one of the most complex structures to handle when there is dynamic analysis involved. One of the influential parameters on these structureschr('39') seismic response is the frequency content of the earthquakes. An index to represent frequency content, which represents frequen...

The past earthquake study conducted on the foundation system (soil and foundation) reveals that the interaction of soil and foundation plays a major role in the response of superstructure. In this regard a literature survey has been carried out on frame structures supported on pile foundation which is in contact with more soil mass as compared to the other type of foundation system. In this res...

This article presents a study of the factors that influence mechanism soil-structure interaction with pilot building having concrete walls and their impact on performance. To illustrate studies carried out, numerical modeling four-floor wall was performed, subjected to vertical actions, supported by slab-on-ground foundation, using Finite Element Method (FEM), together specific 3D software for ...

The present aim of this study is to investigate the effect of different parameters influencing pounding in highway bridges. Pounding is the result of a collision between two parts of the deck and/or the deck and abutments at the separation distance during the earthquake.  In the present study, the period ratio of the adjacent frames, ground motion spatial variation, and soil-structure interacti...

The Supplemental Security Income (SSI) and Aid to Families with Dependent Children (AFDC) programs serve populations with similar characteristics. SSI serves adults and children with disabilities who are in low-income families, and AFDC serves low-income families with children. Because of that overlap, policy changes in one program can affect the other. In 1996, Congress enacted the Personal Re...
