The main objective of this project is to study the performance of wall framernstructures subjected to high eccentric loads. This project aims to investigate therneffect of eccentricity on the lateral force resistance capacity of wall framernstructural systems. It also identifies the members that are highly affected by thisrnhigh story eccentricity and propose ways to improve their strength. This projectrnaims to answer questions like; what is story eccentricity in wall framernstructures? What is the response of wall frame structures with high eccentricityrnwhen they are subjected to lateral loads? what are the parameters that arernmainly affected by story eccentricity? What are the effective measures that canrnbe taken to avoid eccentricity on the structures? rnrnThe performance of twelve different buildings with different story levels and shearrnwall locations has been investigated using ETABS finite element analysisrnsoftware. The building models has been selected to represent wall framernstructures with and without story eccentricity. The analysis and design of eachrnindividual model has been conducted according to Ethiopian building code andrnstandards. Then the analysis and design output results has been compared,rnbriefly interpreted and discussed in order understand the effect of eccentricityrnon the performance of wall frame structures. rnThe project found that the lateral load resistance capacity of wall framernstructures is highly dependent on story eccentricity and may cause failure if notrnconsidered during building design. The increase in eccentricity, increased bothrnthe period and inter story drift of the wall frame structure. The structures withrnhigh story eccentricity required bigger lateral load resisting structures than thernstructure with minimal or without eccentricity. According to its findings thisrnproject recommended to avoid story eccentricities in building design.
