      The standards for the functional design and ultimate design of a tent
      Date: 2017-08-03Read: 1501

      The functional design of a tent

      1 The functional design of a tent should meet the national and industrial standards.

      2 The size of each part of the tent should meet the following requirements:

              (1) The tent’s usable area should be determined according to the number of users and the requirements of its use.

              (2) The tent’s clear side height shall not be lower than 3.85m, and all particular requirements must be met.

              (3) If a glass wall is needed, double tempered laminated glass should be adopted.

              (4) The entrance and exit should be at least 4m wide and 3m high, so that users and items should come in and go out safely.

      3 The fire protection design of tents should meet the national provincial compulsory fire-fighting technical standards.

      A tent should be designed according to the requirements of the engineering use function, load magnitude and equipment installation. In terms of structural system, if a tent is used for rental, a standard structural system should be adopted, since a tent of this structure is easy to assemble, and can be reused given normal maintenance. For tent design, a probability theory-based ultimate limit state design method should be adopted, while a partial factors design expression needs to be used for structural calculations. If a tent is used for rental, the bearing capacity of the hard gable wall, glass gable wall, wall panel and handrail, which only need to possess horizontal carrying capacity (at 1m high, the bottom can be lowered), can be set at 0.5kN/m if there are no special requirements. For a non-public passage, its bearing capacity can be lowered properly, but it shouldn’t be less than 0.3kN/m; the bearing capacity would better not be less than 1.0kN/m if the tent is densely populated.

      Tent structure design

      1 A tent should be designed according to the requirements of the engineering use function, load magnitude and equipment installation. A standard structural system should be adopted, so that the tent will be easy to assemble and reuse given normal maintenance.

      2 For tent design, a probability theory-based ultimate limit state design method should be adopted, while a partial factors design expression needs to be used for structural calculations.

      3 If a tent is used for rental, the bearing capacity of the hard gable wall, glass gable wall, wall panel and handrail, which only need to possess horizontal carrying capacity (at 1m high, the bottom can be lowered), can be set at 0.5kN/m without special requirements. For a non-public passage, it can be lowered properly, but its bearing capacity shouldn’t be less than 0.3kN/m; the bearing capacity would better not be less than 1.0kN/m if the tent is densely populated.

      4 The bearing capacity of the tent floor should meet the requirements of use, and it can be set at 3.5kN/m2 if there are no special requirements for it. For a non-public passage, its bearing capacity can be lowered properly, but it shouldn’t be less than 0.3kN/m2; the bearing capacity would better not be less than 1.0kN/m2 where there are too many users.

      5 The wind load value should be equal to what is specified in Unified standard for the design building structure load, and the impact of membrane materials should be considered. When a tent is applied where the average wind speed is greater than 28m/s, checking calculation should be done on its stability and the wind resistance in the actual condition. A wind resistance test should be conducted as necessary.
