Write-Up: Simplified Reinforced Concrete Design Based on NSCP 2015
1. Load Combinations (Simplified for Gravity + Lateral)
The most common simplified load combination from Section 203.3.1:
- U = 1.2D + 1.6L (for beams, slabs, columns without wind/seismic)
- U = 1.2D + 1.0E + 1.0L (for seismic, per Section 208)
Where:
- D = Dead load
- L = Live load
- E = Earthquake load
Simplified PDFs often provide pre-calculated load tables for typical bay sizes. Simplified Reinforced Concrete Design 2015 Nscp Pdf
Design Procedures
The 2015 NSCP PDF provides detailed design procedures for various structural elements, including beams, columns, and slabs. These procedures include: Where:
- Flexural design: The code specifies the procedures for designing flexural members such as beams and slabs.
- Shear design: The code specifies the procedures for designing shear members such as beams and columns.
- Axial load design: The code specifies the procedures for designing axial load members such as columns.
Core assumptions in simplified RC design
- Use Limit States Design (strength & serviceability).
- Concrete and steel strengths follow specified f'c and fy values (confirm project specs).
- Strain compatibility and Whitney stress-block assumptions for flexural design.
- Use simplified moment and shear resistance equations per code clauses.
- Seismic detailing follows ductility requirements (ties, confinement, lap lengths).

4. Shear Design (Section 421)
- Concrete shear strength (( V_c )): Simplified formula ( V_c = 0.17\lambda\sqrtf'_cb_w d ).
- Spacing limits for stirrups: Closer spacing if ( V_u > 0.33\phi V_c ).
