Work has been conducted on the following project:
Masonry Infill Frames
Project Summary:
Masonry infills are often used in concrete and steel frame buildings as a durable material to separate interior spaces and for exterior walls. If these infills are constructed tight to the surrounding frame elements (columns and beams), then they will have a significant effect on the strength and over-all performance of the building. Whether that effect is positive or negative will depend largely on detailing and the designer’s understanding of this type of construction. Frames with masonry infill constructed tight to surrounding beams and columns is not commonly used in modern Canadian construction, however such infills can have a significant impact on the behaviour (strength and stiffness) of structures that do include them.
Many structures with masonry infilled frames are part of our existing stock of buildings in Canada and it is very important to understand their behaviour when they undergo rehabilitation. Dr. Liu’s research also investigates the development of strategies for designing modern masonry infill construction, including an all-masonry system wherein the beams, columns, and infill are all constructed from concrete block masonry. The project includes advanced computer modeling and analysis techniques as well as testing of infilled frames.
