Can Street Lamp Posts Resist Earthquakes And Winds

Outdoor street lamp posts are an important part of the city's night landscape and an important guarantee facility for nighttime driving and pedestrian traffic safety. However, due to the influence of climate change and environmental conditions, street lamp poles are prone to tilt and break under the action of wind, affecting their normal use and even causing safety hazards to driving and pedestrians. Therefore, the wind stability design and earthquake resistance design of outdoor street lamp posts are very important. Street lamp post wholesaler Phoebus will show you how.

Outdoor street lamp post wind resistance requirements

When designing the wind resistance stability of street lamp poles, their wind resistance needs to be considered. Under normal circumstances, the wind resistance requirements of street lamp poles are as follows:

1. The basic wind resistance load of the steel pole should meet the requirements of the level 3 wind zone under normal use conditions, that is, it can maintain vertical stability when the design wind speed is 24 meters per second.

2. For high poles, special consideration should be given to their wind resistance, and corresponding design plans and monitoring measures should be formulated.

a. Wind resistance stability design of outdoor street lamp post

In order to ensure the stability of street lamp poles under wind force, the wind resistance stability of the pole body needs to be designed. The specific measures are as follows:

1. Increase the bending moment tolerance of the street light pole and improve its damaging wind speed level.

2. Increase the deadweight of the street light pole and improve stability.

3. Adopt an aerodynamic drag reduction design to reduce the wind load of the street light pole.

b. Material selection

In the wind resistance stability design of the street light pole, it is also very important to choose the right material. Under normal circumstances, the material selection of the street light pole should meet the following requirements:

1. Have sufficient wind resistance and bearing capacity.

2. It is not easy to corrode and has a long service life.

3. The material should be cost-effective and not increase excessive costs.

c. Pipeline layout

In addition to the design and material selection of the street light pole, the layout of the pipeline also has an important impact on the wind resistance stability of the street light. Generally speaking, water pipes and control cables should be placed horizontally, which can reduce the wind invasion area and improve the stability of the street light pole.

Measures to improve the seismic performance of outdoor street lamp post

1. Optimize structural design

In the design stage, the stiffness and mass distribution of the street light structure are adjusted to reduce the response to earthquake action. For example, use lightweight and high-strength materials, set up a reasonable support system, etc.

2. Select earthquake-resistant materials

Selecting materials with good earthquake resistance can effectively reduce the impact of earthquakes on street lamp poles. For example, use steel with a high elastic modulus and high strength.

3. Strengthen the infrastructure of street lamp posts

The foundation of the street lamp post is the support of the entire structure. Strengthening the infrastructure can improve the earthquake resistance of the street lamp posts. The foundation design should fully consider the foundation conditions and adopt appropriate foundation forms and materials.
