This is the most complicated part of the code. A good simplified PDF will provide a one-page summary of the basic tension development length (ld) with modification factors for cover, spacing, and lightweight concrete.
Let’s demonstrate why a simplified guide is so effective. simplified reinforced concrete design 2015 nscp pdf link
Given:
(f’c = 28) MPa, (f_y = 414) MPa, (M_u = 180) kN·m, (b = 300) mm, d = 550 mm (assumed). This is the most complicated part of the code
The 2015 NSCP is a copyrighted document by the Association of Structural Engineers of the Philippines (ASEP). Simplified guides like Gillesania’s are also copyrighted. While the NSCP itself is available for purchase in hard copy or via authorized e-book platforms (e.g., TechFactors, Amazon, or local engineering bookstores), no legitimate "free PDF link" exists for the full simplified textbooks. Given: (f’c = 28) MPa, (f_y = 414)
However, the official NSCP 2015 Volume 1 is sometimes made available for free in limited, watermarked form by ASEP for educational review. But a "simplified" version—one with explanations and examples—is a commercial product.
