In the performance- based seismic design, seismic performance of building is differently evaluated according to variant seismic conditions. Most of the application programs for structural design (ETABS, SAP, MIDAS, ANSYS etc.) calculate the performance points of building according to Federal Emergency Management Agency(FEMA), Applied Technology Council -40 (ATC -40)’s seismic building code and parameters. On this paper, we evaluated the seismic performance of building according to our national seismic building code[1] and parameters and maked suggesti- -ons on the design practice.

<p>With the continuous development and progress of society, the structure of high-rise buildings has been paid more and more attention by the engineering community. However, the existing high- rise structure design methods often have a lot of redundancy and have a lot of room for optimization. Most of the existing seismic design methods of high-rise structures are based on engineering experience and manual iterative methods, so that the efficiency of design can not meet the needs of the society. if the method of design automation is adopted, the workload of designers can be greatly reduced and the efficiency of structural design can be improved. Based on the digital modeling theory, this paper proposes a MAD automatic design algorithm, in which the designer provides the initial design of the structure, and the algorithm carries out the modeling, analysis, optimization and design of each stage of the structure, and finally obtains the optimal structure. The structural design module of this algorithm starts from the component level, when the component constraint design meets the limit requirements of the specification, it enters and completes the component constraint design and the global constraint design of the structure in turn. In this paper, taking a ten-story braced steel frame high-rise structure as an example, the optimal design is carried out, and its seismic performance is analyzed. the results show that the MAD automatic design algorithm can distribute the materials to each part reasonably, which can significantly improve the seismic performance of the structure and realize the effective seismic design.</p>

Fragility functions are presented for 15 glazing system configurations in support of Applied Technology Council efforts to develop a performance-based seismic design approach for building performance assessment. The study includes seismic evaluation of curtain wall and storefront systems in terms of probability and the consequences of damage, including economic and life safety consequences. Defined damage states consist of gasket degradation, initial glass cracking and crushing, and glass fallout. Alternatives are offered to the provided prototype fragilities for configurations with differing glazing characteristics, which account for varying glass-to-frame clearance, aspect ratio, and glass panel dimensions. Issues related to applying laboratory-based fragility data to actual glazing systems in the field are addressed.

The seismic performance spectrum is a new kind of the response spectra which is formed according to the designated performance objectives. The performance objectives are changed according to the performance objective level and period of structure, and are different in the acceleration sensitive, velocity sensitive and displacement sensitive range in the seismic performance spectrum. The seismic performance spectrum formulas are derived, which demonstrate the mathematic relationship between the seismic demands of the different performance objective levels and the period of structure. The fitted formulas of the seismic performance spectra for seismic design are obtained due to statistical result of 1085 ground motion records. The new seismic performance spectra are shown in visual three-dimension figures which can represent the seismic demand, performance objective and period of structure in this paper. The philosophy of the seismic performance spectrum is analyzed which reveals the rules for estimating seismic demand of structure at the different performance objective levels. So the multi-objective performance-based seismic design is also proposed using the seismic performance spectrum.

The height of 101-storey Shanghai World Financial Center Tower is 492 m above ground. According to the philosophy of performance-based seismic design, the seismic performance design objectives and corresponding parameters were proposed for the structure under various seismic actions from frequent to rare earthquake levels. Analytical studies including refined finite element analysis, nonlinear time-history analysis, and stress distribution analysis on the important joint have been conducted to evaluate the structural seismic performance. Along with the analytical studies, shaking table model test and the important joint tests have been carried on in order to verify the accuracies of the analytical results as well as to complement the analytical studies. The results obtained from the studies demonstrate that the structural system meets the performance-based design objectives presented in the paper.

The last version of the National Building Code of Canada was issued in 2010. The next version will be issued in 2015. In the code cycle between 2010 and 2015 significant changes have taken place in the seismic design provision. The main factor that drives these changes is an improved understanding of the seismic hazard across the country. Changes have also been introduced in the site effect factors. The structural design provisions have been appropriately adjusted to respond to changes in the estimates of hazard and the new site effect factors. There are also new provisions related to design in regions of low hazard, buildings with flexible diaphragms, buildings with inclined columns, passive energy dissipation systems, base isolation, rocking foundations, glazing systems, racks, and elevators. Some of the changes are briefly discussed. The main focus of the paper is, however, on the revisions to the structural design provisions.

 In seismic design based on performance, seismic performance level is determined based on failure state of the building and seismic design objective is set according to the importance of the buildings. In many countries, they calculate the seismic reaction of the buildings with the use of structural design programs to check the aseismic performance through the nonlinear static analysis method. In this paper, we established seismic performance levels and aseismic design objective to design on the basis of design objective according to the three levels in Seismic Design Code of Building, DPR Korea, 2010.

This paper divided the seismic performance of RC Components into five levels: integrity, slight damage, slight ~ moderate damage and serious damage, which were defined based on material damage. Physical and mechanical description of RC components in each performance level was given, which can be used as the basis of performance-based evaluation of concrete components in microscopic model and the basis of research on deformation index limits in macro components.

In this paper, a simple and practical performance-based seismic design (PBSD) method for regular highway bridges is suggested. In the proposed PBSD method, the drift ratio of the bridge column is employed as quantitative indices of seismic performance levels, and its target values for each seismic performance level are given. The whole design processes of a regular highway bridge with various performance objects under different seismic levels are demonstrated.
