If you are a civil engineering student in the Philippines or a board exam reviewee, you have likely heard one name whispered with a mix of respect and urgency: Besavilla.
For decades, the late Engr. Venancio I. Besavilla Jr.’s review books have been the backbone of the Civil Engineering Licensure Examination. However, there is a common point of confusion: Which edition of his book matches the current NSCP 2015?
Let’s cut through the noise. Here is everything you need to know about the Reinforced Concrete Design by Besavilla PDF, the NSCP 2015 code, and how to use them correctly. Reinforced Concrete Design Besavilla Pdf Nscp 2015
Just downloading the file won’t make you a designer. Here is a proven 4-week study plan:
To truly master Reinforced Concrete Design, one cannot rely solely on Besavilla or solely on the Code. Here is a recommended workflow for students and reviewees:
1. Concept First (Besavilla) Start with a Besavilla chapter (e.g., Rectangular Beams in Flexure). Understand the derivation of the "balanced condition" and the concept of the Whitney stress block. Solve the example problems to get comfortable with the algebra. Download the old Besavilla PDF for one purpose
2. Code Application (NSCP 2015) Once the math is clear, open NSCP 2015 to the corresponding section (e.g., Chapter 4: Concrete Design). Look for the specific constraints.
3. Cross-Reference Units and Notations Older Besavilla editions often use English units (psi, kips, inches). NSCP 2015 is presented in SI units (MPa, kN, meters) though it provides conversions.
4. Focus on Serviceability Besavilla covers deflection and cracking. NSCP 2015 places a heavy emphasis on serviceability limits. Ensure that your designs do not just meet strength requirements but also satisfy deflection criteria (Table 4.3.1.1 in NSCP 2015). and finalize bar selection and spacing.)
Problem summary (concise):
(You would perform numeric iterations for As, check a, z, etc., and finalize bar selection and spacing.)
Besavilla Approach: Often solves for the "balanced condition" ($k_b$) using a coefficient method derived from linear elasticity.
NSCP 2015 Approach: Uses Whitney’s Stress Block (Rectangular Stress Block).
Shear is checked separately: calculate shear demand Vu and compare with shear capacity Vn (concrete contribution + shear reinforcement). NSCP 2015 sets criteria for when shear reinforcement (stirrups) is required and spacing limits. Torsion is treated with interaction checks combining torsion, shear, and bending, with additional transverse and longitudinal reinforcement as required.
