SSI Effects on the Behavior of a Low-Rise Load Bearing Masonry Building Including Foundation

Based on the analysis for damages of masonry structure from Wenchuan earthquake, the seismic behavior of multi-story masonry school building is analyzed, and the seismic behavior with load-bearing structural system of longitudinal wall is mainly discussed. Based on the analysis and study, several problems which need more attention to the seismic appraisal and reinforcing design are pointed out, and finally the differences and correlation of seismic appraisal, as well as seismic design are discussed.

Hollow Brick

The research aims at conducting a quality research with Reinforcement of a hollow brick wall. The empty internal sections significantly lower the dead load. With a better surface finish, the side of the block was cast, minimizing the cost of plastering. Several sample mixes are tested to achieve a finished surface. The respective frames were cast with and without reinforcement and the test results were compared. The blocks were used to build masonry walls and ' load-bearing strength ' of the walls was tested. It is possible to use the reinforced hollow block as a load-bearing wall. Nearly 75 percent of the deaths related to the earthquake in the last century,Buildings have collapsed, the majority of which (more than 70 percent)is due to the collapse of buildings made of masonry. Most of the properties in India are Unreinforced Masonry (URM) buildings that are weak and vulnerable even under moderate earthquakes and that function on the wall due to high wind forces, causing severe damage to high wind loads and it is recognized that Reinforced Masonry Building has many advantages over unreinforced masonry building.The use was very limited in Indian building practices and there are still no approved codes and shear walls were used in most constructions, even in mild earthquakes, instead of reinforced masonry walls

The City

A significant number of old unreinforced load-bearing masonry (URM) buildings exist in many countries worldwide, but especially in Europe. In particular, Bosnia and Herzegovina has an important stock of masonry buildings constructed from the 1920s until the 1960s without application of any seismic code, due to their nonexistence at that time. With the 1963 Skopje earthquake, this class of buildings were shown to be rather vulnerable to seismic actions, which exhibited serious damage. This article assesses the seismic vulnerability of a typical multi-storey residential unreinforced load-bearing masonry building located in the heart of Sarajevo, which may be exposed to an earthquake of magnitude up to 6 by Richter’s scale. The buildings of this kind make up to 6% of the entire housing stock in the urban region of Sarajevo, while in Slovenia this percentage is much higher (around 30%). The analysis of a typical building located in Sarajevo revealed its drawbacks and the need for some kind of strengthening intervention to be implemented. Additionally, many structures of this type are overstressed by one to two additional floors (not the case of the analyzed structure) constructed from 1996 onwards. This was due to the massive population increase in the city center of Sarajevo and further increased the vulnerability of these buildings.

Building Components

The application of textile reinforcement can help to increase the load-bearing capacity of masonry building components, especially those subjected to lateral loads caused by wind, earth pressure or earthquake. The reinforcement can be applied externally or be integrated in the bed joint. The key part of an ongoing research project is to investigate the bonding and load-bearing behavior of masonry building components reinforced with textile in thin bed joints with the aim to develop reinforcing elements. With these reinforcing elements for bed joints the construction of basements and higher buildings will be more attractive with masonry. In the first part of the project, the relevant material and bond properties of preselected materials were determined, and a suitable textile was selected. In the second part, four-point bending tests on unreinforced and reinforced masonry wall specimens were carried out in order to investigate the effectiveness of bed joint textile reinforcement to increase the masonry flexural tensile strength. In the third part, a proposal for the design of prototypical reinforcing elements will be worked out. This paper deals with the two first parts of the research project.

Tibial Condyle

SummaryTotal removal of a knee joint meniscus is followed by osteoarthritis in many mammalian species. Altered load-bearing has been observed in the human knee following meniscectomy but less is known about biochemical effects of meniscectomy in other species. Using pressure sensitive paper in sheep knee (stifle) joints it was found that, for comparable loads, the load-bearing area on the medial tibial condyle was significantly reduced following medial meniscectomy. Also, for loads of between 50 N and 500 N applied to the whole joint, the slope of the regression of contact area against load was much smaller. Following medial meniscectomy, the ability to increase contact area as load increased was markedly reduced.The load bearing area on the medial tibial condyle was reduced following meniscectomy.
