Seismic Stabilisation, otherwise known as earthquake engineering is a form of engineering that analyses structures such as buildings, with earthquakes in mind. The main goal is to ensure that a structure is resistant and will not be damaged in minor shaking, and to avoid serious damage or collapse in the event of a major earthquake.
A seismic performance assessment is the quantified level of the actual or anticipated seismic performance associated with the direct damage to an individual building subject to a specified ground shaking that an engineer will need to know. This can be done either experimentally or analytically.
At HSR we have a qualified team of professionals who understand the features of seismic performance in different structures such as adobe, limestone and sandstone, timber frame, light-frame, reinforced masonry, reinforced concrete, prestressed and steel structures.
The majority of chimneys use reinforced brick masonry, as a result of this they are also one of the most visibly damaged part of any building. Reinforcing chimneys is sound practice in areas of seismic risk, and in areas subjected to high winds.
There are three methods to reinforcing a new chimney and ensuring structural stability, these methods include vertical reinforcement grouted inside the chimney, horizontal reinforcement placed in the mortar bed and anchor straps or cabling securing the chimney to the buildings frame.
