High tall buildings are more susceptible to dynamic excitations such as wind and seismic excitations. In this paper, design procedure and some current applications of tuned mass damper (TMD) were studied. TMD was proposed to study response of 20 storey height building to seismic excitations using time history analysis with and without the TMD. The study indicates that the response of structur...

Abstract— Though the structures are supported on soil, most of the designers do not consider the soil structure interaction and its subsequent effect on structure during an earthquake. Different soil properties can affect seismic waves as they pass through a soil layer. When a structure is subjected to an earthquake excitation, it interacts the foundation and soil, and thus changes the motion o...

Abstract M oment R esisting (MR) einforced C oncrete (RC) frame system presented in the current seismic design standards and required to on-site action develops soft storey mechanisms. In practice, idealized theorized ductile response specified for this structural type does not occur. these conditions, research study presents a logical scheme regarding development method of MR RC system. The ma...

Saying goodbye to the old and ready for the challenges of the new, RCN President Maude Storey delivers a special New Year message to the College membership.

the concept of soft sets, introduced by molodtsov [20] is a mathematicaltool for dealing with uncertainties, that is free from the difficultiesthat have troubled the traditional theoretical approaches. in this paper, weapply the notion of the soft sets of molodtsov to the theory of hilbert algebras.the notion of soft hilbert (abysmal and deductive) algebras, soft subalgebras,soft abysms and sof...
