MASONRY CONSTRUCTION

Characterised by its load-bearing capacity, simple handling and long durability, masonry is one of the oldest building materials in use today. A masonry structure’s appearance can vary and today's masonry structures meet strict requirements with regard to mechanical and structural-physical properties. Modern masonry is either reinforced or unreinforced when produced. The behaviour of the brick and joint components in masonry has a decisive impact on load-bearing behaviour, crack and deformation behaviour and the stress-strain relationship. Cracks and deformation will appear in masonry bonds under tensile and shear loads; slightly uneven surfaces or dirt in contact joints will cause high local pressures or high restoring forces will occur when horizontal deformation is prevented. Using construction bearings reduces horizontal constraint forces and compensates local pressures. Bearings also prevent spalling caused by large rotation angular deflections/torsions while the masonry load-bearing capacity is increased by centred load transmission. Sliding bearings are used when there is a need to transmit high loads through sliding connections with low coefficients of friction. Elastomeric sliding bearings absorb temperature-induced changes in length of the connected components as planned.
