The Difference Between Seismic Support And Load-bearing Support
Oct 10, 2021
The traditional load-bearing support can only bear vertical loads. When an earthquake occurs, the lateral swing amplitude is large, which is easy to damage the surrounding facilities. Eventually, the building's electromechanical engineering system suffers different degrees of damage. Therefore, the difficulty of later maintenance is increased. The use of traditional load-bearing brackets does more harm than good. Look at the seismic support, but it is a support system firmly connected to the building structure with seismic force as the main load. Once the building encounters an earthquake of fortification intensity, the seismic force generated by the pipeline and equipment can be transmitted to the structure through the seismic support and hanger, so that the small earthquake can be repaired, and the large earthquake can not fall. The anti-seismic effect greatly reduces the cost of earthquake resistance and achieves the goal of long-term earthquake resistance and safe earthquake resistance.
The differences between traditional load-bearing supports and seismic supports are described as follows:
1. The traditional load-bearing support system is a support system with gravity as the main load (traditional gravity supports and hangers only bear vertical loads)
1) Large lateral swing, destroying nearby facilities, or even falling off;
2) Lack of supporting structure for horizontal seismic action;
2. Seismic supports and hangers mainly bear the load in the horizontal direction of the pipeline
1) Earthquake-resistant supports and hangers are arranged to change the dynamic characteristics of the pipeline system, changing from flexible to rigid, and the response under earthquake action is significantly reduced;
2) Change the force of the gravity hanger at the seismic support and hanger, and then change its design, type selection, stiffening, anchoring, etc.;
3) Seismic supports and hangers are divided into vertical and horizontal supports and hangers. Their stress, layout, and anchorage involve knowledge of multiple disciplines, such as earthquake engineering, structural engineering, mechanical engineering, and water supply and drainage.
