Buildings which are located within an earthquake-prone region are expected to be retrofitted to ensure that they are safe to live in. The level of risks in a story structure depends on different soft-story structures. They include open parking which is usually on the ground floors and ground retail shops that are enclosed with windows. Such structures do not provide enough sturdiness required to withstand a seismic movement. Here are a few techniques for apartment buildings seismic retrofit to consider.
Infill walls reinforcement. Infill of walls is done to reinforce the inner side of a wall. Therefore, concrete or other types of infill are set up on the walls of soft-story structures. Using this method increases the weight which is pressed on the foundation hence the need of adjustments to accommodate this change. Using this method is effective but does not improve the ductility of the entire structure.
Additional of braces. Steel and concrete braces are used to connect the initial framing of a structure to avoid leaving disconnections which weaken the structure. The continuous structure which is made through this process makes the building to be stiff enough to withstand movement during an earthquake. One can adopt various bracing methods such as buckling, restrained bracing, steel bracing, and other types.
Base isolation. Base isolation is an interesting mitigation measure which includes putting bearings between the substructure and superstructure of the base. This method is used to allow energy to dematerialize in a significant manner. Therefore, the movement of the structure is reduced since there is no continuous base.
Consider the use of energy removal devices. Vibration and other forms of energy are familiar during an earthquake. Therefore, implanting devices which can remove these energies from the surface of a structure reduces the possibility of collapse. Some of the devices that can be used include viscoelastic, hysteretic and friction dampers.
Use of smart materials. Cutting technologies have been adapted recently to reduce the possibility of risks in a story structure. The most common smart materials that are in the market include aramid fiber and carbon fiber reinforced plastic. They are sheets which are wrapped on beams to improve their ductility and durability. The use of these devices is cost effective and can be used in areas with high earthquake levels.
Other approaches that can be considered. There are other methods to use in this process. They include a precast retrofit shear system using special connections and the Aoki seismic method. The Aoki method uses steel pipes which have friction dampers on the external walls to work as energy dissipation strategy. Also, selective weakening technique can also apply in story structures. In this procedure, selected places in a building are weakened and then improved. The weakening procedure is done to prevent brittle failure.
Choose a professional firm which is affiliated with this practice to ensure quality outcomes. Even so, consider all the structural policies which are in place, your budget and the level of earthquake that can hit your region. Apart from that, secure quality materials used in the specific method which you have concluded on. Take time to compare all the companies which are at your disposal and consider one which has the most reasonable pricing. It should also have enough resources to use your favorite strategy.
