engineering highlighted the conceptual and practical limitations of the Code oriented design methods. All these facts are using liable wind design and assessment approach evidently describing the performance of highrise building to wind loads beyond the current design wind loads. Hence, philosophically logical extension of the current wind design is performance-based wind design. Performance-based engineering is a modern engineering process through which a new structure is designed, or an existing building is evaluated more efficiently and economically by requiring the structure to meet certain performance requirements at various levels of demand. Comparing to the current perspective approach, utilizing the performance-based approach results in more informative and transparent output .
performance-based wind analysis of RCC and steel structure We can more effectively design structures assess to the performance-based wind design approach. Wind effects are considering for high-rise structures and steel structure. Performance based wind design gives the different wind load patterns for checking the performance of structure against wind. In this paper, a brief review is based on performance-based wind design of tall structure, steel structure with non-linear analysis. In this project work, an attempt is made to fully understand the method and process used in performance-based wind design and nonlinear design of the building.

The Structural Engineering Institute of the American Society of Civil Engineers published a pre-standard for PBWD of tall buildings (ASCE2019). The pre-set and are outlines an alternative and comprehensive approach to building design for wind loading, which explicitly evaluate occupant comfort, building drift and extreme wind event behaviour. While PBSD methodologies used worldwide for over 25 years, the development of similar techniques for the design of building for wind hazards has lagged behind. Several concerns have slowed the application of wind design, including duration and directionality of loading, element fatigue, conceptual methods, wind tunnel techniques, and dynamic response. The Pre standard was created to address these concerns and chart a path forward for implementation of PBWD.
1. INTRODUCTION The performance-based engineering concept was developed and used in the seismic engineering field. It is used in professional practice for seismic design and devaluation. For performing PBWD of wind-excited buildings, it is necessary to have a understanding of structural responses in the nonlinear inelastic range. Performance-based wind design requires performanceobjectives, analysis methods such as nonlinear static pushover and nonlinear time history analysis under wind loads, and mechanisms to reduce and, if possible, to eliminate damage accumulation. As the wind flows against a building, the resulting force acting on the elevations is called the ‘wind load’. The building’s structural design resist wind forces and efficiently and transfer them to the foundations in order to avoid structural collapse.
The Pre standard used for detailed evaluation of building response requires detailed understanding of their leant wind environment. Therefore, the building analysis and design arepshows a result on conducting wind tunnel testing to calculate structural loads. These structural loads calculate by using one of three methods of linear or nonlinear response history analysis. In this work, a similar type of concept will be used to analysis and design of tall building for performance-based wind design nonlinear response history analysis.
The structural response of typical, roof pitch, gableend, industrial buildings, in a wind storm is dependent on the wind loads used in the design of cladding and the frame structure. Building codes and guidelines define the required performance via the specification of minimum structural performance requirements under wind load. Since this approach intends to keep the structural system elastic, the more efficient design may be achievable by allowing controlled inelasticity in structural components. However, recent studies in earthquake and wind
