📚 12 NEW ENGINEERING GUIDES — free on rhcetools.com
We just published 12 step-by-step guides on the topics engineers and CE students search for most. Every article has the governing formulas, a fully worked numeric example, assumptions & limitations, and an FAQ — written for NSCP 2015 / ACI 318 practice and paired with our free online calculators.
REINFORCED CONCRETE DESIGN
🔹 Design of a Singly Reinforced Concrete Beam (NSCP 2015) — complete worked example
🔹 One-Way Slab Design Step by Step — thickness, moments, main bars & temperature steel
🔹 Isolated Footing Design — bearing, one-way & punching shear, flexure
🔹 RC Column Design — axial capacity, longitudinal steel & tie requirements
🔹 Minimum Beam Depth for Deflection Control — the L/16, L/18.5, L/21 table explained
🔹 Crack Width Check — Gergely-Lutz method with a worked example
🔹 Rebar Development Length & Lap Splice per ACI 318-19
ANALYSIS & LOADS
🔹 Simply Supported Beam Formulas — shear, moment & deflection for common load cases
🔹 NSCP 2015 Load Combinations Explained — ultimate (LRFD) & service, with examples
ESTIMATING & SITE PRACTICE
🔹 How to Compute Rebar Quantity for Slabs, Beams & Columns
🔹 Concrete Mix Ratios & Quantity Estimation — bags of cement, sand & gravel per m³
🔹 How to Read Structural Drawings — beam, column & slab schedules explained
Made for civil engineering students, CE Board Exam reviewers, structural engineers, QS/estimators, and site engineers who want the "why" behind the numbers.
