Friction Pendulum Bearing (FPB for short) is a kind of widely used device to improve seismic capacities of building and bridge structures. Despite the considerable progress made in developing theoretical models to understand the mechanical behaviour of FPB, these models mostly focus on the horizontal movement behaviour and rarely on the rotational behaviour of FPB. However, rotational displacements of FPBs indeed will occur along with horizontal displacements in earthquakes and may affect the structural seismic performance. Motivated from these findings, a theoretical model of FPB that describes the rotational behaviour is established based on the moment balance theory in this paper. A set of rotational tests are carried out to validate the theoretical model, and comparisons of experimental and theoretical results show that they are in good agreement. The theoretical model developed in this paper will help understand the structural seismic performance more accurately in the case of rotations of FPBs.

The Earthquake in 2005 has destroyed a large part of the Khyber Pakhtunkhwa Province (Pakistan) and Kashmir which has created questions regarding the adequacy of framed structures in order to resist strong motions, as due to this earthquake many buildings were damaged badly or were devastated. In order to evaluate the framed structure’s performance under future expected earthquakes, a non-linear static analysis i.e. Push over analysis has been carried out. So for achieving our objective of analysing the framed structure’s performance under seismic loading, a 4 storey’s framed structure was selected and analysed. From the results that were obtained from this study shows that the framed structures which are properly designed under gravity will perform in a safe zone under seismic loading. Certain response parameters predicted by each pushover analysis which were obtained from Gravity & Earthquake load patterns were analysed and compared with each other for differences. The observations made from the current study clearly showed that pushover analysis results depend on three factors i.e. 1-the load path, 2-structure properties and 3-features of the ground motion. The response parameters were estimated by applying the displacement of target at the control node. The accuracy of the predictions depends mainly on the approximations involved in the theory of the procedures, structural properties and features of ground motion.

The construction industry has recorded an unprecedented advance in recent years, especially in the world recent developed countries and this involves the increasing development of insulation techniques against the effects of seismic actions that can threaten the structure integrity at a certain time. Most recent achievements in terms of structure insulation systems are successfully used within building and bridge structures in order to ensure the optimal stability level during a potential earthquake, which allows ensuring a proper safety level both for operation and in terms of investments protection. the protection methods of the structures are directed in two directions, namely in achieving the insulation at the base of the structure by strategically positioning the systems at the base of the structure while the second direction is directed at seismic energy consumption or energy dissipation by using dissipative systems mounted on frames the resistance structure of the building. By combining the action of the two types of mechanical systems, good results can be obtained regarding the behaviour of the structure isolated by the earthquake. The paper presents constructive aspects of the mechanical systems used for the seismic insulation of both building and bridge structures and their functional role in the whole structure to which they are mounted. Through the experimental tests made are highlighted the better results in terms of acceleration for the structure isolated with the composed system. Are emphasized in this manner the protective system role in ensuring an improved behaviour for the structure where is mounted at seismic dynamic motions that can occur in time.
