Building Design And Construction Vicente Tagayun Pdf May 2026

Most modern PDF guides tell you to "add control joints." Tagayun’s book asks you to check the foundation settlement first. He provides a flowchart: Is the crack vertical (shear) or diagonal (settlement)?

Tagayun integrates the National Building Code of the Philippines (PD 1096) directly into his design exercises. He teaches you not just how to design a staircase, but why the riser/tread ratio must comply with Code.

Let’s extract a hypothetical lesson from the PDF. Assume you are designing a simple residential beam (span: 6 meters, load: 20 kN/m). Building Design And Construction Vicente Tagayun Pdf

Step 1: Determine the Ultimate Load (Factored)
Tagayun uses the classic: Wu = 1.2 DL + 1.6 LL (consistent with NSCP).

Step 2: Moment Calculation
Mu = (Wu * L^2) / 8 for a simply supported beam. Most modern PDF guides tell you to "add control joints

Step 3: Reinforcement Ratio (ρ)
Here is where Tagayun provides a shortcut table. Instead of solving quadratic equations, he gives a "ρ-table" for f’c = 20.7 MPa (standard concrete). You look up Mu and find required steel area (As).

Step 4: Selection of Bars
Tagayun famously advises: "Use 16mm or 20mm bars only. Avoid 25mm in residential—too hard to bend manually." He teaches you not just how to design

Step 5: Detailing
He includes a sketch showing where to cut off top bars (at L/4 from support) and bottom bars (at midspan). This saves the contractor steel costs.

Without the PDF, you’d rely on expensive software. With it, you can hand-calc in 10 minutes.
