大梁模板验算(国外英文资料) The garage girder template and support check Calculate the maximum beam section 300mm x 3500mm, the face plate 15mm thick wood plywood, 50mm by 100mm wooden square to do the second time, the distance 250mm; Φ 48 x 3.5 common steel family back leng, spacing is 300 mm, the bowl worksite, horizontal distance of 900 mm, step distance of 1200 mm. Load calculation (the template is considered in three consecutive terms) The template structure is self-weighted Slab form 0.50 kN/m2 times 0.3 = 0.15 kN/m [the 4th edition of the manual of construction: 8-65] Floor template and bracket 0.75 kN/m2 times 0.3 = 0.225 kN/m The new concrete weighs itself 24 kN/m3 times 0.3 times 3.5 is 25.2 kN over m [the 4th edition of the manual of construction: 8-65] Reinforced self-respect 1.5 kN/m3 times 0.3 times 3.5 is 1.575 kN/m [the 4th edition of the manual of construction: 8-65] Load caused by vibrating concrete 2.0 kN/m2 times 0.3 = 0.6 kN/m [the 4th edition of the manual of construction: 8-65] 1.2 panel examination (plate width 1.0 m). 1.2.1 bending strength test = (0.15 + 25.2 + 1.575) * 1.2 + 0.6 * 1.4 = 33.15 N/mm (for the carrying capacity) Is equal to 1/8 times 33.15 times 2502 is equal to 50 times 104 N times mm = x 103 mm3 = 13N/mm2 is equal to 15N/mm2 1.2.2 anti-shear tests Is equal to 1/2 times 33.15 times 250 is 4.14 times 103 N = 0.276 N/mm2 is less than or equal to (= 1.2 N/mm2) 1.2.3 deformation check = (0.15 + 25.2 + 1.575) * 1.2 = 32.32 N/mm (for the degree of flexibility) I = bh3/12 = 1000 * 153/12 = 0.281 * 106mm4 E is equal to 5,000 times 0.5 is 2500 N over mm2 = 0.37 is less than or equal to [omega] = l / 400 = 250/400 = 0.63 mm Meet the requirements 1.3 time keel examination (the template is considered for three cross-purposes) 1.3.1 bending strength test = (0.15 + 25.2 + 1.575) * 1.2 + 0.6 * 1.4 = 33.15 N/mm (for the carrying capacity) = 0.10 times 33.15 times 2502 = 0.2 times 106 N · mm = 83 x 103 mm3 = 1.2 N/mm2 is equal to 13N/mm2 1.3.2 anti-shear
