According to the masonry standard the compressive strength is basically dependent on factors such as the mortar strength and the relative values of unit and mortar strength. However interlocking brick has none or less use of mortar. Therefore there is a need to investigate the behavior of masonry walls using interlocking bricks. In this study a series of tests have been conducted; physical prop...

Original scientific paper Reinforced-concrete (R/C) frames infilled with masonry wall, especially with the presence of an opening, are insufficiently explored structural elements. We have experimentally investigated influence of the opening’s type and position to the lateral response of reinforced-concrete frames with masonry infill. Correction factors, that take into account influence of the o...

Masonry infill walls are the standard solution to build envelopes and partitions in reinforced concrete buildings southern Europe. In Portugal, masonry appeared sixties, with massive use of frames for residential commercial buildings. Since then until our days infills (cavity walls) have not experienced significant changes, apart from some variations thickness introduction thermal isolation bet...

This paper presents first a valid, fully non-linear 2-D numerical model that can capture realistically the in-plane hysteretic behaviour of reinforced concrete (R/C) frames with masonry infills when they are subjected to combined vertical and cyclic horizontal loads in order to predict their post-elastic earthquake bahaviour. The effectiveness of this simulation was validated by comparing the n...

Since being introduced in 1963, silicone resin emulsion paint (SREP) has developed into one of the most modern facade coating systems. While specific formulations and raw materials have changed in the last 42 years, the long-lasting performance properties resulting from the unique combination of water repellency, vapour permeability, low VOC and the silicon-resin based structure have remained c...

This paper presents an analytical approach to describe the behavior and mode of failure of infill masonry structures strengthened with fiber-reinforced polymer (FRP) materials. The approach is used to simulate the response of strengthened infill masonry walls under the effect of out-of-plane uniformly distributed pressure simulating wind pressure. The approach includes a finite element analysis...

Masonry buildings, when subjected to external temperature fluctuations, tend to regulate them either by storing heat in their thermal mass or by offering it back to the interior, with a time lag depending on the thermal capacity of the building and characterized mainly by the overall mass of the masonry. This time lag may vary from a few hours when lightweight masonry is concerned to several da...
