In addition to having knowledge of the mezzanine floor, we should also have knowledge of the live load that is specified in the Ministerial Regulation No. 6, issued under the Building Control Act, B.E. 2522,
Note : Mezzanine Floor is a shelf. suitable for storing materials parts of the product which can create additional space on the high side of the building worthwhile by making a mezzanine floor It is a large structural system that is strong and durable. can bear a maximum weight of 1,000 kg / square meter, please contact rnbproduct
Which this requirement is appropriate to apply to buildings. short (Buildings up to 18 m tall) are summarized in the following sections of this guideline.
(1) uniform the loads Details are as follows.
The optimum live load in the design of a building or other structure must be The maximum load expected to be applied to the respective building, but in any case shall not be less. than the constant load on the same type as specified in the Ministerial Regulation No. 6, issued under the Building Control Act, B.E. 2522
(2) Point load (concentrated loads)
Payload acts as a point. Details are as follows. Floors or other similar surfaces must be designed to be able to support evenly distributed loads. Has been defined in the Ministerial Regulation No. 5, issued under the Building Control Act B.E. Others, the point force may be assumed to be a live load uniformly spread over an area of 0.75 x 0.75 m and is fixed at the point where the maximum force is applied to the building element.
(3) Load from partition toads
The payload from the partition is as follows. In office buildings and in other buildings or mezzanine floors where the position of the partition changes. Partition weight requirements must be established. Whether the partition is indicated in the construction documentation or not, unless the stated live load exceeds 400 kg/m. from the partition must be no less than the flat live load of 75 kg/m.
(4) Reduction in live loads
The minimum uniform flat load specified in Ministerial Regulation No. 6 in Clause 15 is permitted the attenuation specified in Clause 19 where you attenuate appropriately for the element. Buildings are based on building stages. Refer to the reduction factor from the table in item 19.
(5) the weight distribution of the floor slabs (distribution of floor loads)
The live load distribution of the slab is specified in IBC 2012 section 1607.11 as follows.
When the evenly distributed flat load on the slab is applied to the design of the correct feeder, Provided for continuity of transfer. The minimum load to be applied shall be the constant load on all span lengths plus the floor live load on the span lengths. The greatest force is exerted in each position under consideration. The load on the slab can be attenuated under As specified in the Ministerial Regulation No. 6 in item 19
1.2.3 Roof tive loads
The payload on the roof is as follows:
The supports for the roof structure and the marquee must be designed. to be able to resist the wind and earthquake In addition to the fixed weight of the structure and Appropriate live load specified in this section. The live load acting on an inclined surface will is assumed to be a vertical force acting on the surface of the object
1.2.4 wind loads
In this section, it is the part that summarizes the requirements from the standards for wind load calculation and response of buildings, Department of Public Works and Town Planning, 2007, and has prepared a sample calculation to apply wind load. with steel structure buildings properly The Department of Public Works and Town & Country Planning, 2007, in part 1, requires that wind force be calculated according to MR.Por.1311-50, chapters 1-2, which covers content. are as follows
(1) General requirements
(2) Calculation of equivalent static wind load by a simple method
For a guideline on the analysis of low-rise buildings (Mor.Por.1311-50, Chapter 2 for the main wind-force resistant system and exterior walls), which will be arranged in a model form. Easy to apply to various types of buildings and roofs suitable for steel structure buildings.
The procedures summarized in this section are applicable to buildings with flat and hipped roofs with pitches from 0 to 90 degrees, single-slope roofs with pitches from 0 to 30 degrees, roof pitches ranging from 0 to 30 degrees. continuous with slopes ranging from 0 – 45 degrees, sawtooth shaped roofs with tightening from 0 – 30 degrees, which the average height of the roof is assumed to be no more than 23 meters and the height of the eave must be less than or equal to the inner distance Minimal building horizontal Net wind load tables have been prepared for terrain types A and 8. These procedures are for completed buildings and are not suitable for buildings in between. installation For other conditions, refer to MDR. 1311-50.
1.2.5 How to calculate gross weight
Calculation of total payload from static payload Live payload Earthquake or wind load together with other loads shall be in accordance with the Ministerial Regulation No. 6 issued under the Building Control Act B.E. 2522 or other related standards such as ASCE 7 etc.
