this paper presents a macro model to predict unreinforced masonry structures in plane behavior. the model is based on the concept of multilaminate theory. in the past, the method has been used to model behavior of soil, disregarding the cohesion and the tensile strength. regarding its mathematical base, and the possibility of applying in other cases, this method is used to predict the ultimate ...

according to non-existence of accurate inspection tools on various steps of design and construction of buildings in the past, also due to any change in function of some structures and finally of seismic activities of residential regions of the country, vulnerability assessment of existing structures is necessary. evaluation of vulnerability of the structures is classified in two categories, qua...

This report describes a non-linear method of analysis for prestressed concrete structures which predicts behaviour at all stages of loading, from the initial application of prestress up to and beyond the collapse condition. The method uses a segmental line element approach and is a modification of an existing method previously developed for reinforced concrete structures. Comparisons with the r...
