In this paper the complete analytical solution concerning the linear soil pressure on rigid spread rectangular footings is formulated. All five distinct regions on the eccentricity map are related to five possible types ...

The frequency response of nonproportionally (or nonclassically or non-Raleigh) damped linear lumped mass systems is discussed here. The exact method, via Laplace transforms, is presented and the practical difficulties ...

This paper forms a literature survey on lumped and distributed parameter, linear, viscously damped, dynamic systems, possessing non-classical modes.

Although the response of undamped or at least proportionally damped linear systems can be determined easily by modal analysis, the prediction of the response of nonproportionally damped linear systems requires either more ...

Due to earthquakes, many structures suffered extensive damages that were attributed to the torsional effect caused by mass, stiffness or strength eccentricity. Due to this type of asymmetry torsional moments are generated ...

In this article, a number of design approaches for 3D reinforced concrete (RC) buildings are formulated in the framework of structural optimization problems and are assessed in terms of their performance under earthquake ...

The objective of this paper is to obtain the optimum design of 3D reinforced concrete buildings in terms of their performance under earthquake loading. This goal is achieved by considering the minimization of the ...
