Vietnamese Standard TCVN 2737:2023 specifies the load and impact on parking garage floors, applicable to the design, construction, and inspection of buildings with parking garage floors.
The design of parking garage floors must ensure that they can withstand the load of vehicles and other activities taking place on the floor. TCVN 2737:2023 provides detailed regulations on the types of loads to be considered, including:
- Dead Load: The weight of the floor itself, surface coverings, walls, columns, and other fixed components.
- Live Load: The weight of vehicles, people, and goods moving on the floor. This is an important factor to be carefully considered when designing the parking garage live load.
- Wind Load: The pressure of wind acting on the floor.
- Earthquake Load: The impact of earthquakes on the floor.
- Impact Load: The impact of vehicles colliding with the floor’s components.
TCVN 2737:2023 categorizes parking garage floors into different classes based on the design load. Correctly identifying the parking garage floor class is very important to ensure the safety and durability of the structure.
Factors affecting the parking garage live load:
- Vehicle Type: The weight and size of the vehicle determine the load acting on the floor. Parking garages for trucks will have higher live load requirements than parking garages for cars.
- Number of Vehicles: The density of vehicles on the floor affects the total distributed load.
- Vehicle Arrangement: The way vehicles are arranged on the floor affects the distribution of the load.
TCVN 2737:2023 also specifies methods for calculating the parking garage live load, including:
- Calculation method based on uniformly distributed load: Applicable to floors with evenly distributed vehicle density.
- Calculation method based on concentrated load: Applicable to floors with concentrated loads at specific locations.
Compliance with TCVN 2737:2023 helps ensure:
- Safety for users: Parking garage floors are designed safely, avoiding the risk of collapse.
- Durability of the structure: Parking garage floors have good load-bearing capacity, extending the life of the structure.
- Economic efficiency: Optimized design helps save construction costs.
Conclusion:
Applying TCVN 2737:2023 correctly in the design, construction, and inspection of parking garage floors is extremely important to ensure the safety, durability, and economic efficiency of the structure. Accurately determining the parking garage live load is a key factor in the design process. Consulting and strictly complying with the regulations in this standard will help investors and construction units create high-quality and safe parking garage structures.
