Stiffness And Damping

This paper aims to study the deformational behaviour of tensile-type viscoelastic dampers under different earthquake excitation directions. A method for calculating the corresponding equivalent additional stiffness and damping of a self-centring-segment bridge pier is derived. Using the displacement-based seismic design method, a design method for self-centring-segment bridge piers with tensile-type viscoelastic dampers is proposed. Using the proposed method, a self-centring-segment bridge pier is designed. Based on dynamic analysis of the finite element model by OpenSees, the effectiveness of the proposed seismic design method is validated.

Displacement Based Seismic Design

According to lots of documents previously studied, a seismic design method is put forward based on displacement for steel moment frame. This method is established in condition that the yield displacement of steel frame can be determined by its geometrical dimension; then the objective displacement (ultimate displacement) can be determined in light of performance level of the structure, and the corresponding coefficient of ductility can be obtained. Thereafter, the design base shear of steel frame structure can be calculated by the use of reduced elastic spectrum. Thus, the design of stiffness and capacity can be conducted on steel frame structure. The analysis of case study indicates that the displacement-based seismic design method addressed herein is of reasonable safety and reliability, and of operational convenience, which can still realize the seismic design of steel frame structure at different performance levels.

Seismic Design Method

A thirteen storey, two bay, reinforced concrete framed structure is subjected to a series of non-linear, dynamic analyses in an attempt to find some correlation between the damaging potential of various digitised earthquakes and their relative strengths which have been computed in a variety of ways. Much of the previous work in this field has been with respect to simple one degree of freedom systems and these do not appear to give any indication of the correlation that could be expected for a non-linear multi-degree of freedom structure. The results show the effects of the different scalings of the various earthquakes and compare these with those obtained for the familiar North-South component of the May 18, 1940 El Centro earthquake. These results highlight the difficulty of trying to relate the use of such a dynamic earthquake analysis to the present pseudo-static code requirements. Further, the results of the analyses show also the great difference between the present assumption of the plastic hinge distributions, used in the ultimate seismic design method, and those observed during the earthquake excitation with the consequences on the lower-floor column axial loads.

This paper presents an overview of the current state of knowledge with regard to literature on Performance based seismic design method. Performance-based earthquake engineering (PBEE) comprises the design, evaluation, and construction of structures performing during design earthquakes and extreme earthquakes to the desires / needs of owners, user, society and environment. The general promise of performance based design is to produce engineered structures with predictable performance during future earthquakes. Presented in this paper is an updated literature review of the Performance -based Seismic design (PBSD) method. Performance based Seismic design is an elastic design methodology done on the probable performance of the building under different ground motions. The derivatives of the PBSD method, known as the Performance ¬based Plastic design (PBPD) and Displacement-based seismic design (DBSD) method that has been widely recognized as an ideal method for use in the future practice of seismic design has also been reviewed.
