Analysis of Partially Infilled Frames
Abstract: The design of building structures is usually carried out without considering the effect of masonry infill. Currently, seismic design codes (Eurocode 8-Part 1, ASCE 41-06) contain provisions for the calculation of stiffness of fully infilled frames mainly by modelling infill as a diagonal strut. However, such provisions are not provided for infilled frames with openings. The main objective of the study was to validate the equations relating the lateral stiffness …
