Structural Design & Construction
"Future Engineer! Dito tatayo ang mga structures mo - from design to actual construction! Master both the theory and the practice."
CELE Challenge
Structural Design and Construction - from concept to completion!
PART A: STRUCTURAL ANALYSIS
1. Types of Loads (NSCP)
Dead Load (D)
Permanent: Concrete 24 kN/m3, Steel 77 kN/m3
Live Load (L)
Residential 1.9 kPa, Office 2.4 kPa
Wind Load (W)
P = qz x G x Cp
Earthquake (E)
V = (ZICW)/R
2. Stress Formulas
Axial: sigma = P/A
Bending: sigma = My/I
Shear: tau = V/A
Torsion: tau = Tr/J
PART B: DESIGN
3. RC Design (USD)
- Flexure: phi Mn >= Mu (phi = 0.90)
- Shear: phi Vn >= Vu (phi = 0.75)
- Beam: Mn = As fy (d - a/2)
PART C: CONSTRUCTION
4. Project Scheduling
CPM
ES, EF, LS, LF, Float = LS - ES
Critical Path: Float = 0
PERT
te = (a + 4m + b)/6
5. Earthwork
- Average End Area: V = L(A1 + A2)/2
- Prismoidal: V = L(A1 + 4Am + A2)/6
CELE Pro Tips
- - Always check load combinations - use the critical one!
- - CPM problems: Draw the network diagram first!
- - Memorize phi factors for strength design
