Vibration control of single floor seismically excited structure using active ma...
Bhatti, A. Q.; Varum, H.The purpose of this paper is to dampen the vibrations using active mass damper (AMD) flexible structure has been tested using Shake Table by linear cart. The active and passive mass properties has been discussed. An observer based state-feedback card controller was used for one floor AMD using MATLAB/SIMULINK modelling. Several laboratory experimental setup using AMD, general system description, model, paramete...
Seismic vulnerability assessment and evaluation of high rise buildings in Islam...
Bhatti, A. Q.; Varum, H.; Alam, Z.Primarily the aim of this research is to carry out seismic evaluation study of buildings structures in Islamabad in order to propose basic guidelines and suggestions for Pakistan Code. Knowing the important nature of the subject, the earthquake based organizations are serious to compile a document for seismic threatened countries and areas. It is aimed that the document will work as a guideline source for the s...
Application of performance based nonlinear static pushover analysis for seismic...
Bhatti, A. Q.; Varum, H.Seismic retrofitting of already constructed buildings is one of the most effective methods of decreasing the risk. However the seismic performance of the structure may not be improved by Strengthening unless the professional engineer selects an appropriate modifying technique based on seismic evaluation of the already constructed structures. In this paper nonlinear static pushover analysis has been performed fo...
Comparison between the visco-elastic dampers and magnetorheological dampers and...
Bhatti, A. Q.; Varum, H.A number of studies have been carried out to investigate the performance of visco-elastic dampers (VEDs) and Magnetorheological dampers (MRDs) in controlling the seismic response of buildings but very few studies regarding the effect of temperature on the behavior of those dampers. As the energy absorption properties of the VEDs are dependent on the ambient temperature, excitation frequency and strain amplitude...
