Light steel keel gypsum board wall height is how to determine

Light steel keel gypsum board wall height is how to determine

Answer:

There is no specific rigid provisions, the specific height according to the actual situation to the scene. Light steel wall commonly used for each root is 3 meters long, if the actual height beyond too much, you can order.
According to the British standard BS5234, different use of the partition wall has different stiffness requirements, the maximum height of the partition wall to determine the criteria for a certain surface load W conditions, the wall of the maximum deflection y does not exceed L / 240; The maximum deformation can not be greater than the L / 240 well system under the 200Pa uniform load. The wind load is superimposed and the uniform load will become larger
D = <l 240 Parameter Description: d: Maximum deformation of the component under uniform load, unit mmq: Uniform load, unit Pa, test In the composition of the material, the cross-sectional nature of the wall stiffness coefficient: EI value of the test to determine the length of the wall The use of 15mm plate instead of 12.5mm plate, the wall stiffness EI can be increased by 33% 2. The keel spacing from 600mm to 400mm, wall EI value increased by 50% 3. The keel spacing reduced from 400mm to 300mm, the wall EI value increased by 50% 4. keel on the wall than the non-buckle wall, EI value increased by 60% 5. Use type I keel than the use of C-keel, EI value increased by at least 100%. The effect of thickness on the EI value is very small relative to several other factors, EI is called bending stiffness, 75 keel spacing is 400, double-sided single layer 12mm gypsum board wall EI = 4.6 × 1010 according to the actual test EI value of the structural partition system: (unit: N.mm2, 1010)
