Methods For Non Ductile Buildings Seismic Retrofit
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 measures to reinforce the columns. Buildings which have column support are supposed to be augmented using different measures. This includes measures such use of reinforced concrete, steel plate winding, aramid fiber, and carbon fiber. Carbon fiber and aramid are the best measures since they are easy to install and do not add a lot of weight to the building foundation.
Consider bracing the building using steel. Steel bracing is a common method that is used in strengthening the building against seismic movements. Columns are braced using X-shaped steel braces inserted between the columns and beams. The use of steel is lighter compared with the addition of resisting earthquake. It also allows light inside the building through the opening formed by the steel braces.
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.
Comply with the regulations provided by construction authorities. Authorities that are responsible for building in areas which are prone to earthquakes have provided regulations related retrofitting measures. It is important to acquaint with them and implement them early enough to avoid the demolition of your building due to non-compliance.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
