Steel grades used in mezzanine construction

The construction of an industrial factory or mezzanine floor must have the Thai Industrial Standards Institute (TIS) of the Office of Industrial Product Standards, Ministry of Industry.

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

1.2 Considered payload

Consideration of loading weight for buildings that are used as industrial factories and warehouses or mezzanine floor be in accordance with the requirements specified in the Building Control Act, B.E. 2522 and related ministerial regulations. as well as standards for considering different types of loads, such as wind load calculation standards and Response of the building (Jun. 1311), building design standards for earthquake resistance (MOP 1301/1502) of the Department of Public Works and Town & Country Planning. Ministry of the Interior, etc.

1.2.1 Definitions

Key definitions used in this guideline References are made to design standards and relevant engineering calculation standards. The details are as follows.

(1) Importance factor means a value that considers the level of risk. affecting life, health and welfare, which is related to property damage or loss of opportunity to use Important keywords have been identified for consideration. The wind and seismic loads in the Department of Public Works and Town & Country Planning standards, which include these priorities, depend on the type of risk. A summary is provided in Table 1.2.1(a) of this guideline.

(2) Deflection means the deformation caused by the static load, live load, seismic load, other loads, playing two towers shall not exceed The limit values, as in Table 2.2.1(0), are presented in Chapter 2, Section 2.2, for consideration. Lateral movement and deflection There will be different criteria for consideration, that is, deflection depends on the length of the structural parts. while the movement The side will depend on the height of the building.

(3) Dead load means the weight of construction materials that are consolidated. Into the building, consisting of structural members, walls, floors, roofs, ceilings, stairs, partitions that are permanent structures. facial decoration material Exterior building walls and other parts that are included in the architecture and structure. and also to the weight of the equipment used Can be moved such as crane rails, water pipes and fire hoses. Electrical conduits, cooling and air conditioning systems and automatic sprinkler system

Note: Usually in the construction of prefabricated steel structure buildings. device weight use that cannot be moved means The additional fixed load (Coklateral load) is different from the payload. because that is part One of the building systems provided by fabricators of industrial buildings and warehouses. by other fixed loads such as partitions that are permanent structures finishing materials, and containing pouring beams (see Table 1.2.1 (b) for general terms that may be used to guide the weight designation). additional permanent load)

(4) Live load means the weight arising from the use of buildings or other structures, excluding the load from construction and the environment such as wind load, rainwater load. earthquake force The force caused by the flood or fixed loading weight. The consideration of live loading weight in the design of prefabricated steel structure buildings from – Ministerial Regulation No. 6 is summarized in part 1.2%.

(5) Roof live load means the load on the roof that occurs (1) during maintenance by workers, equipment and materials (2) during service life. works of buildings by movable objects such as potted plants or other small decorative items unrelated to building use; (3) by use of roofs such as rooftop gardening or focal points Phon Remarks – The load on the roof does not include wind loads and moving plates. or fixed payload as stated above

Table 1.2.1 (a) Important Factors

Remarks Remarks The precedence for seismic forces is specified in the Building Design Standards. Earthquake tremor 1301/1302-61) of the Department of Public Works and Town & Country Planning. Ministry of Interior in Table 1.5-1, and the significance values for wind load are specified in the standard for wind load calculation and building response (MOP 1311 (50)) of the Department of Public Works and Town & Country Planning. Ministry of Interior in Table 2-2

Refer to the earthquake resistance food design standard (MorPor. 1301/1302-61) of the Department of Public Works and Town & Country Planning, Ministry of Interior.
