How to Read Structural Drawings: Beam, Column, and Slab Schedules Explained for Site Engineers and Students
A practical, code-agnostic walkthrough of sheet organization, grid lines, and member marks, then how to actually read beam, column, slab, and footing schedules -- with mock tables, standard bar notation, and the site mistakes that most often slip past a rushed reading.
Reinforced Concrete Column Design (NSCP 2015 / ACI 318): Axial Capacity, Longitudinal Steel, and Tie Requirements
Size tied RC columns per NSCP 2015 / ACI 318: axial capacity formula, steel ratio limits, tie size and spacing, and slenderness screening, with two fully worked numeric examples.
Concrete Mix Ratios and Quantity Estimation: How Many Bags of Cement, Sand, and Gravel per Cubic Meter
Class AA to C Philippine concrete mix ratios plus the standard cement, sand, and gravel estimating tables, the dry-volume derivation behind them, 40kg vs 50kg bag conversions, and worked slab, footing, and column take-offs.
NSCP 2015 Load Combinations Explained: Ultimate (LRFD) and Service Combinations with Examples
All seven NSCP 2015 ultimate (LRFD) load combinations plus the ASD service combinations, with the f1 live-load factor, why 0.9D matters for uplift, and two fully worked examples: a beam under wind and a column under seismic axial force.
One-Way Slab Design (NSCP 2015 / ACI 318) Step by Step: Thickness, Moments, Main Bars, and Temperature Steel
Step-by-step one-way slab design per NSCP 2015 and ACI 318: minimum thickness, ACI moment coefficients, main steel, and a full 3.5 m worked example.
Isolated Footing Design (NSCP 2015 / ACI 318): Bearing, One-Way and Punching Shear, Flexure -- Worked Example
Full square isolated footing design worked step by step: bearing area from net allowable pressure, factored soil pressure, two-way punching and one-way shear, flexural steel, bar development, and dowels, per NSCP 2015 / ACI 318.
