The inelastic response of existing reinforced concrete (RC) buildings without seismic details is investigated, presenting the results from more than 1000 nonlinear analyses. The seismic performance is investigated for two buildings, a typical building form of the 60s and a typical form of the 80s. Both structures are designed according to the old Greek codes. These building forms are typical fo...

Soft storey buildings are characterized by having a storey which has a lot of open spaces. This soft storey creates a major weak point in an earthquake. Since soft stories are classically associated with retail spaces and parking garages, they are often on the lower stories of a building, which means that when they collapse, they can take the whole building down with them, causing serious struc...

Water content affects mortar and masonry properties however, it is often determined by the mason assessing mortar workability. This can lead to lack of consistency and variable masonry performance. This paper investigates the compressive, flexural and bond strength and stiffness of brick masonry bound with natural hydraulic limes (NHL2, 3.5 and 5), hydrated lime (calcium limeCL90s) and cement-l...

Traditional Chinese wood residences consist of timber frames with masonry infill walls or other types infill, representing valuable heritage. A field investigation traditional village dwellings in northern China consisting mud and stone was conducted. Their construction characteristics are reported, static cyclic tests were performed on two full-size wood-stone hybrid different configurations (...

Interior brick-infill partitions are usually considered as non-structural components and only their weight is accounted for in practical structural design. In this study, their effect on the progressive collapse resistance of an RC building subjected to sudden column loss is investigated. Three notional column loss conditions with four different brick-infill locations are considered. Column-los...

This paper examines how the decision to include (or exclude) masonry infill walls in modelling of non-seismically designed RC framed structures can affect results EC8-3 seismic assessment process. A frequently used macro-modelling technique for simulation panels within bounding members is first reviewed. case-study application follows which a sample structure carried out, with and without consi...

Strengthening of un-reinforced masonry (URM) structures to improve its seismic performance is not only well recognized among the research community but also getting attention of practicing engineers around the globe. The estimation of lateral capacity and performance of masonry becomes complex because of heterogeneous nature of its constituent materials and other associated problems. Heterogene...

This paper documents performance of cast-in-place reinforced concrete (RC) buildings in the Durrës municipality during Albania earthquake November 26, 2019 (MW 6.4). Both mid- and high-rise RC were affected by earthquake, experiencing structural and/or non-structural damage even collapse some cases. The authors performed a reconnaissance study after involved seismic assessment area. Besides obs...
