“…This implies that the equivalent static forces are derived primarily based on the elastic dynamic response of fixed-base structures without considering soil-structure interaction (SSI) effects. The efficiency of using the code-specified lateral load patterns for fixed-base building structures has been extensively investigated [6][7][8][9][10][11][12][13][14][15]. The results of these studies indicated that the current design approach, in general, does not lead to a uniform distribution of deformation demands in multi-story structures.…”

The lateral load distributions specified by seismic design provisions are primarily based on elastic behaviour of fixed-base structures without considering the effects of soil-structure-interaction (SSI).Consequently, such load patterns may not be suitable for seismic design of non-linear flexible-base structures. In this paper, a practical optimization technique is introduced to obtain optimum seismic design loads for non-linear shear-buildings on soft soils based on the concept of uniform damage distribution. SSI effects are taken into account by using the cone model. Over 30,000 optimum load patterns are obtained for 21 earthquake excitations recorded on soft soils to investigate the effects of fundamental period of the structure, number of stories, ductility demand, earthquake excitation, damping ratio, damping model, structural post yield behaviour, soil flexibility and structural aspect ratio on the optimum load patterns.The results indicate that the proposed optimum load patterns can significantly improve the seismic performance of flexible-base buildings on soft soils.

“…n is the number of frame span in the specific direction and i h is the height of i'th story from base. Value of Mpc1 can be determined by using the condition that no soft story mechanism would occur in the first story, when a factor of 1.1 times the design lateral forces are applied on the frame (Leelataviwat S et al 1999). Assuming that plastic hinges form at the base and top of the first story columns, the corresponding work equation for a small mechanism deformation gives:…”

Most structural design codes use elastic analysis to calculate and distribute seismic base shear over the height. This may lead to unsuitable design and may cause undesirable damages to the structure. To solve this problem, in recent years the Performance-based Plastic Design (PBPD) method which considers the plastic behavior of the structure, has been proposed. In this study, the PBPD method is extended to the dual system of moment and eccentrically braced frames. As a code requirement, in dual systems the moment frame must be able to resist at least 25 percent of the base shear. In the proposed PBPD method, the shear resistance of each system is selected at the beginning of design process and this criterion can be contributed to the design process directly. In this regard, three 6, 12 and 20 story structures are designed based on PBPD and conventional method. To assess the behavior of each system, nonlinear pushover and time history analysis are conducted. Results show that dual frames that are designed by PBPD method have less stiffness and strength than frames that are designed by ordinary method. However the yield mechanism is controllable and plastic deformation capacity of structures are better conducted to design in PBPD method. The results also show that the collapse probability of frames that are designed by PBPD method is acceptable.

“…The performance based design (PBD) (SEAOC 1999;Leelataviwat et al 1999) introduces a new and general framework in seismic design of structures by defining performance levels and objectives. Thus, three to five structural performance levels are defined and should be achieved for increasing levels of earthquake actions by satisfying performance objectives for every performance level.…”

ΑBSTRACTA new method for seismic design of plane steel moment resisting framed structures is developed. This method is able to control damage at all levels of performance in a direct manner. More specifically, the method: a) can determine damage in any member or the whole of a designed structure under any given seismic load, b) can dimension a structure for a given seismic load and desired level of damage and c) can determine the maximum seismic load a designed structure can sustain in order to exhibit a desired level of damage. In order to accomplish these things, an appropriate seismic damage index is used that takes into account the interaction between axial force and bending moment at a section, strength and stiffness degradation as well as low cycle fatigue. Then, damage scales are constructed on the basis of extensive parametric studies involving a large number of frames exhibiting cyclic strength and stiffness degradation and a large number of seismic motions and using the above damage index for damage determination. Some numerical examples are presented to illustrate the proposed method and demonstrate its advantages against other methods of seismic design.
