Passing the board exam is the immediate goal, but practicing engineers also keep a Besavilla NSCP 2015 PDF on their work laptops. Why?
To illustrate why the "2015" keyword is critical, consider this classic Besavilla-style problem:
Problem: Determine the nominal moment capacity (Mn) of a singly reinforced beam: b=300mm, d=500mm, As=3-25mm bars, fc'=28 MPa, fy=415 MPa.
| Parameter | NSCP 2010 (Old) | NSCP 2015 (Correct) | | :--- | :--- | :--- | | β1 for fc'=28 | 0.85 | 0.85 (No change) | | εt for tension-controlled | 0.005 | 0.005 (No change) | | Φ (for flexure) | 0.90 (if εt>=0.005) | 0.90 (same) | | Development length Ld | ~984 mm | ~1,020 mm (due to modifier) | Reinforced Concrete Design Besavilla Pdf Nscp 2015
If the problem involved shear (stirrups), the 2015 code changes Φ from 0.85 to 0.75 – a 12% reduction in capacity. If your Besavilla PDF references the old Φ, your beam would be under-reinforced in shear—a catastrophic failure mode.

When merging these two resources, students often make the following mistakes:
NSCP 2015 modified the basic development length for deformed bars in tension: [ l_d = \frac340 \fracf_y\lambda \sqrtf’_c \psi_t \psi_e \psi_s d_b ] Besavilla’s PDF dedicates entire sections to simplified tables and shortcuts for common bar diameters (16mm, 20mm, 25mm, 32mm)—a lifesaver during the exam.
This tutorial teaches reinforced concrete (RC) design using the Besavilla method aligned with the 2015 National Structural Code of the Philippines (NSCP 2015). It covers fundamentals, design philosophy, material properties, load combinations, flexural design (beams and slabs), shear, development and anchorage, column design, detailing requirements, and example problems. Each section gives step-by-step procedures and worked examples so you can apply the method to real projects. Passing the board exam is the immediate goal,
Note: This tutorial assumes familiarity with basic mechanics, statics, and elementary structural analysis.
For decades, civil engineering students in the Philippines have relied on Gillesania's and Besavilla's review books. However, a significant challenge arises when using classic Besavilla texts: many were written using the Working Stress Design (WSD) method or older ACI 318 codes.
The NSCP 2015 (based largely on ACI 318-14) mandates the Strength Design (SD) method (Load and Resistance Factor Design). To effectively use Besavilla for modern review, one must understand how to translate the concepts. To illustrate why the "2015" keyword is critical,
