INFLATABLE TENTS – HANGAR 15X30

Product catalog summary

Information on the Contract
The project involves determining the number and strength of anchors required to support wind and snow loads for a self-supporting inflatable tent with a 15x30 meter rectangular base. The client is INFLATABLE TENT INC- M2B INFLATABLE.

Summary
LARO EXPERTS-CONSEIL was tasked with establishing the number of anchors needed to withstand wind and snow loads for an inflatable tent to be installed in various public places in Canada. The tent is a self-supporting inflatable structure with a dome-like roof, measuring approximately 15x30 meters at the base and 9.98 meters in height. The analysis considered wind and snow constraints.

Description of the Structure
The tent has a rectangular base of 15x30 meters and a dome-shaped roof. It is a self-supporting inflatable structure with walls composed of pressurized air between two flexible membranes. Wind loads considered include gusts of 50 km/h, 70 km/h, and 120 km/h. The structure complies with CAN ULC S109 and NFPA 701 requirements and can resist a 150 mm height of snow load.

Wind Loads
The structural analysis modeled wind loads on different axes at speeds of 50 km/h, 70 km/h, and 90 km/h. The wind load was simulated using wind tunnel simulations.

Modelization - Simplified Model
A simplified model was used for analysis, which slightly overestimates the reaction values at the supports. This ensures wind resistance through ground anchoring and bracing.

Analysis
The analysis evaluated three different wind gust speeds, affecting the number of anchors and pullout resistance required. Table 1 summarizes the wind velocity and anchors required: 50 km/h requires 850 lbs pullout resistance and 24 anchors; 70 km/h requires 1500 lbs and 24 anchors; 120 km/h requires 2900 lbs and 24 anchors.

Conclusion
The analysis concludes that each anchorage must comply with the requirements outlined in Table 1. The structure's safety is ensured by adhering to these specifications.

Inflatable tents – Hangar 15x30 | LARO experts-conseil SUMMARY The mandate given to LARO EXPERTS-CONSEIL aims to establish the number of anchors required to withstand wind and snow loads. The tent will be installed in various public places in Canada. To achieve this goal, the inflatable structure was modeled with several simplifications and was evaluated under wind and snow loads. The mandate is thus to ascertain the number of anchors required to withstand wind forces, in addition to the resistance necessary to avoid their pullout. This document is written based on the technical data provided...

Inflatable tents – Hangar 15x30 | LARO experts-conseil DESCRIPTION OF THE STRUCTURE INFLATABLE TENT INC- M2B INFLATABLE provided all technical data. The tent discussed here has a rectangular base whose dimensions are 15x30 meters and its roof forms a dome with a square base, bringing the structure to its highest level, 9,98 meters. The structure is a self-supporting inflatable type, and its walls are composed of pressurized air between two flexible membranes. The wind loads considered in this report are established at gusts of 50 km/h, 70 km/h and 120 km/h. ( 75 mph). Comply with CAN ULC S109...

Inflatable tents – Hangar 15x30 | LARO experts-conseil ANALYSIS In this analysis, 3 different wind gust speed were evaluated. These speeds affect the number of anchors and/or the pullout resistance required by each anchor as shown in Table 1 – wind velocity and anchors required. There is no maximum number of anchors to stabilize the structure as long as the minimum total pullout resistance is respected. Minimum total pullout resistance (lbs) 50 850 70 1500 120 (75 mph) 2900 Minimum number of anchors 24 24 24 TABLE 1 – WIND VELOCITY AND ANCHORS REQUIRED. FIGURE 4 : ANCHORS REACTIONS IN VERTICAL...
