梁板柱取值范围(国外英文资料) To view the article The beam, column and board section are evaluated April 15, 2010 12:00 P.M. The principle of beam, column and board cross section The column is according to the design of concrete structure, gb50010-2002. The size of the smallest side of the column is 300mm, but the general frame column in the project is not less than 400mm. Two, the beam one, the frame beam (1), the beam width commonly take 250mm, 300mm, 350mm (2) 1/10-1/13 of the span of the beam The second beam (1), width is 200mm, 250mm (2) the beam is 1/10-1/14 The suspension girder is usually one quarter to one sixth of the cantilever The commonly used beams are: 250, 300,... , 750, 800, 900, 800. The commonly used beam width is: 120, 150, 180, 200, 220, 250, 300, with 50 modulus increasing. In the present water structure, the main girder should be at least 50mm higher than the second beam, if the lower bar of the main beam is double-deck, or if the transverse reinforcement is applied, it should be 100mm higher. Economic quarter: 1.7-2.7 m, main beam: 5-8m, second beam: 4-6m. The principle of cross section size The number of the serial number type is more than a continuous cantilever One beam ~ The whole rib is now cast 2 main girder ~ The whole rib is now cast Three independent beam Four frame girder Now the frame girder is cast 5 frame beam ~ Assemble the integral or assembly frame girder 6 frame flat beam ~ The steel reinforced concrete frame flat beam is now cast 7 frame flat beam ~ Prestressed concrete frame flat beam Three, Under normal load, the thickness of plate is 1/36-1/45, but not less than 100mm (individual room should not be less than 80mm). The minimum height ratio of the plate The type of the plates supporting form Single board double to board plate without beam floor Jane is 1/35 1/45. 1/40, 1/50, 1/12, 1/30. Note: the calculation span of plate thickness/short side direction Frame beams, column dimensions and materials [from concrete structures] P437] The se
