Non-ductile structures are considered to have high fatality numbers during an earthquake. These kinds of structures are characterized by having concrete floors, roofs which are supported by concrete walls and columns. The rigidity form of these structures leads to a limited ability to absorb the shock during an earthquake. Relevant retrofitting measures must be considered to ensure that these buildings can withstand seismic activities. Here are a few methods for non ductile buildings seismic retrofit to be considered.
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.
Addition of reinforced concrete resisting walls. This method is used in strengthening the walls of a non-ductile structure. This measure is done to walls that have low resistance capacity which makes it suitable enough. However, it adds the weight of a structure to its foundation. Therefore, necessary precautions should be considered to avoid adding a lot of weight more than the pressure that the foundation can accommodate.
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.
Consider the seismic-isolation measures. Seismic-isolation is considered to reduce the effect of structural shaking. It considers the use of various devices and technology as well. You expect common devices such as rubber and lead which are capable of absorbing the rate of shock produced. The most common technique that is used involves isolating specific rooms and floors using a complex system.
Consider the shake control measure. This kind of technology provides relevant measures to control the shaking of a building. It involves measures such as the installation of a large water tank on the roof or a suspended mass in the roof. Besides that, a ceiling damping method is used to control the shaking of the ceiling. It can as well use a built-in dumper which is installed at the exterior part of a building.
Ensure that you are compliant with all the regulations provided. Most construction authorities expect all non-ductile buildings to be retrofitted within a given window. Failure to observe these regulations within the stipulated period, the respective buildings can end up being demolished. Therefore, building owners should hire experienced companies to analyze their structure and decide on the most suitable retrofitting measure.
