Non-ductile buildings have recorded the highest number of fatality during an earthquake. As a result, such types of structures must be retrofitted effectively to reduce the chances of collapsing during an earthquake. Their high risks are caused by the rigidity of concrete which makes them incapable of absorbing earthquake shocks. Different measures can be considered to reduce the risk of collapsing for such kind of building. Below are factors to consider in non ductile buildings seismic retrofit to take into consideration.
Use relevant column reinforcing measures. Buildings that are supported by columns require to be reinforced using various methods. These methods include the use of carbon fiber reinforcement, aramid fiber steel plate winding, and additional reinforcement concrete column pouring. Concrete pouring usually increases the weight of the building on its foundation which can work as additional reinforcement if the foundation is strong enough.
Use internal bracing method. Internal bracing is considered in buildings which are supported using columns between two different floors. The braces are installed in a cross-sectioned form between the beams and columns. Steel is strong and quite durable compared with other materials. The cross-sectioned braces allow light to enter the building during the daylight which makes it unnecessary to add other lights.
Add reinforced concrete on the wall. Weak walls must be reinforced to ensure that they withstand earthquake shock. This method does not apply to every wall making it less costly and effective. However, it adds the weight on the foundation which can be a disadvantage or advantage according to the weight capacity of the respective base.
Use ceiling clipping technology. Ceiling clipping technology is a cheap method that is used to reinforce ceilings using a conventional method. The clips are attached to the main base of the ceiling and improve the holding capacity of the ceiling material. These clips are affordable, easy to install and produces an aesthetic appeal to the house interior.
Seismic-isolating methods. This process involves the use of technology that reduces the effect of shake produced by an earthquake on a structure. It involves the use of seismic-isolating devices and technology. Some of the devices that can be used include rubber and lead which can absorb the shock produced during earthquakes. These devices can reduce the level of structure vibration to about one third to one fifth during an earthquake.
Acquaint with relevant shake control measures. Various effects result from a shaking building. This risk can be reduced through the installation of a tank or a heavy material on the top of a building and using ceiling damping devices. Building owners can as well adopt built-in dampers which are external braces that have built-in damping systems.
Make sure that you have complied with all regulations concerning this process. Construction authorities within earthquake-prone areas have established strict measures and deadlines supposed to be observed by structure owners. As a building owner, you should hire a reliable company to assess the condition of your house to avoid placing it under the risk of demolition. This is considered if the measures are not undertaken within the provided time.
