3.5. Tính toán cốt thép cho sàn tầng điển hình
Vật liệu sử dụng :
- Bê tông B30 Rb = 17 MPa, Rbt = 1.15
- Thép CB240-T Rs = 210 MPa ; Rsw = 170 MPa - Thép CB400-V Rs = 350 MPa ; Rsw = 280 MPa
Tiết diện tính toán bxh = 100x15 (cm)
Giả thiết a = 15 mm h0 = h – a = 15 – 1.5 = 13.5 cm αm = M
γbRbbh02 → ξ = 1-√1-2αm ; As = ξγbR
bbh0 Rs
Kiểm tra hàm lượng cốt thép:
μmin = 0.05% ≤ μ = As
bh0 ≤ μmax =ξrγbRb
Rs = 2.784%
