The seismic design of building mechanical and electrical engineering seismic support engineering is an indispensable important link in the seismic resistance of building structures, so. The seismic support and hanger can provide reliable protection to the construction electromechanical engineering facilities in the earthquake, receive the earthquake action from any level target, and greatly reduce the damage to the construction electromechanical engineering facilities by the earthquake. Its composition is composed of anchors, reinforced booms, seismic connection members and seismic braces.
How is the seismic support designed and what is the scope of the design?
1. Design basis for seismic support
1. According to the "Code for Seismic Design of Buildings" GB50011-2010, 3.7.1 (Strong Bar) non-structural components, including building non-structural components and building ancillary mechanical and electrical equipment, the link between itself and the main structure should be designed for earthquake resistance.
2. In accordance with the "Code for Seismic Design of Building Electrical and Mechanical Engineering GB0981-2014, 1.0.4" (Strong Bar), the electrical and mechanical engineering of buildings in areas with a seismic fortification intensity of 6 degrees and above must be designed for earthquake resistance.
2. Description of seismic support design
1. Design scope: ≥DN65 water supply, hot water, fire fighting, air-conditioning water pipes or other equipment with a gravity exceeding 1.8KN, rectangular cross-sectional area greater than or equal to 0.38m2 and circular pipe diameter greater than or equal to 0.7m in the air duct should be set Seismic support and hanger
2.Electrical piping with inner diameter not less than 60mm or cable ladder, cable trough box and busway with gravity not less than 150KN/M should be designed for seismic support and hanger.
Anti-seismic support, once added anti-seismic facilities to the suspension system. When an earthquake occurs, the lateral and longitudinal seismic supports can greatly reduce its disorderly shaking. Under the condition of complete seismic function of the overall building, it can ensure that the suspension system does not fall, which greatly reduces the casualties and staff injuries caused by secondary disasters. Economic losses.
