For most simplified designs, assume f'c = 21 MPa (for beams/slabs) or 28 MPa (for columns), and fy = 414 MPa.
Columns are compression members. The simplified design often assumes that the column is "short" (slenderness effects are negligible) and loaded axially.
Traditional reinforced concrete design involves iterative calculations, interaction diagrams, and complex strain compatibility. "Simplified" methods refer to:
The National Structural Code of the Philippines (NSCP) is the adopted code of practice for structural engineering in the country. The was a major overhaul, adopting principles from the American Concrete Institute (ACI 318-14). However, in 2021 , the Association of Structural Engineers of the Philippines (ASEP) and the Philippine Structural Engineering Society released critical updates and errata to the 2015 NSCP.
The 2015 edition adopts the reorganization of , significantly changing how technical information is structured. Key technical shifts include:
Step 2: Calculate Concrete Shear Capacity ($V_c$). For simplified design, NSCP allows: $$V_c = \frac16 \sqrtf'_c b_w d$$
