“…Seismic loading provisions in the existing building codes focus on the minimum lateral seismic forces for which the building must be designed, but don't explicitly incorporate the demand and response characteristics. However, the specifications of the lateral forces alone is not enough to ensure the desired level of protection in a building when subjected to expected earthquakes of different intensities [6].…”

“…Starting about 1990, the international design community began to be interested in the development of performance-based design concepts. Whereas current building code provisions are prescriptive in nature and require that buildings be designed with minimum specified strength and stiffness, performance based procedures permit the designer to directly demonstrate that a design is capable of meeting certain standard performance objectives, independent of meeting prescriptive strength and stiffness criteria [5][6][7].…”

Structures are designed using current seismic design codes which are mostly based on Force-Based Design approach. The aim of the work is to implement the Performance-Based Seismic Design (PBSD) approach in concrete buildings. PBSD, which is a new concept in seismic design of structures, is a reliable approach capable of providing more detailed information on the performance levels of both structural and non-structural elements. Methods. In this study Performance-Based Seismic Design has been utilized on reinforced concrete irregular frame. In order to do this pushover analysis was done. Story drift ratios were chosen as deformation limits to define the performance levels for specific earthquake hazard levels. The results of this study show that Performance-Based Seismic Design gives a structure with better seismic load carrying capacity, thereby achieving the objective of performance as well as economy. It is also possible to conclude that PBSD obtained by above procedure satisfies the acceptance criteria for immediate occupancy and life safety limit states for various intensities of earthquakes.

“…while others determined the performance level of frames [9]. Kasimzade et al [13] attempted to raise the structure's maximum load-carrying capacity by adding a new criterion that required many plastic hinges in the structure, and the results showed that the load-bearing capacity of the frame-bearing system increased by 50% compared to that resulted from the code methods. On the other hand, some research evaluated seismic code design methods.…”

In the present decades, more advanced seismic nonlinear analysis has become possible. ATC-40, FEMA-356, Eurocode, the N2 method, and FEMA-440 are popular performance-based seismic design (PBSD) procedures. These procedures determine the performance level of the structure and the target displacement using the nonlinear static behavior of the structure and the damped response earthquake spectrum. The main objective of this paper is to evaluate the performance of regular frames designed by the Egyptian code equivalent static load method using several performance design methods. The studied regular RC frames are six, ten, and fourteen-story limited ductile concrete frames. The SeismoStruct nonlinear finite element program was used to perform the pushover nonlinear static analysis. The maximum inelastic displacement and the performance level of the reinforced concrete buildings were determined for each performance method. In general, it was concluded that the equivalent static method is conservative, especially for tall frames, because it is based on simple linear assumptions. The results of this paper showed that the performance level of regular concrete frames designed by the ECP-201 seismic code method subjected to 0.15g and 0.3g, was a life safety level. Also, the capacity spectrum method (ATC-40) gave the lowest target displacement in most cases, and the displacement coefficient method (FEMA-440) gave the highest value.
