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 introduces a finite element scheme and a systematic calibration approach for masonry infilled RC frames. The modeling scheme combines the smeared crack approach with discrete crack elements to allow for the opening of diffused flexural and dominant shear cracks. It is, therefore, able to capture the nonlinear material behavior and the interaction of the infill wall with the bounding ...

Accurate modeling of masonry has been a major concern of the researchers in the past decades. Besides reinforced and unreinforced masonry structures, masonry can be found in frame structures as infill panels which are used as partitions and/or external walls. These elements role as a part of structure and introduce a large degree of nonlinearity into the system. In this study, a micro-modeling ...

PURPOSE This work investigated the proton tissue-equivalence of various 3D printed materials. METHODS Three 3D printers were used to create 5 cm cubic phantoms made of different plastics with varying percentages of infill. White resin, polylactic acid (PLA), and NinjaFlex plastics were used. The infills ranged from 15% to 100%. Each phantom was scanned with a CT scanner to obtain the HU value...

A reinforced concrete building with masonry infill is most common type of construction in India. Traditionally, conventional clay bricks or blocks which are heavy rigid materials have been used as Infill wall. Though, AAC (aerated light weight concrete) lightweight, flexible that provides insulation and fire resistance lower impact on environment, can be (MI) material buildings. now also availa...
