The Importance of Accurate Calculations
Inadequately sized footings can lead to uneven settlement, structural instability, or permit rejection. StruCalc’s tools—including a concrete footing calculator, deck footing calculator, and embedded post calculator—ensure engineers can size isolated, continuous, and embedded elements with precision. With support for various loading conditions and soil types, StruCalc provides quick, compliant calculations that streamline the design process and improve project safety.
Footing and Post Calculator FAQs
What Types of Footings Can StruCalc Analyze?
StruCalc’s footing calculator modules support the analysis of:
- Isolated (Spread/Pad) Footings – Square, rectangular, or circular footings supporting columns or posts.
- Continuous (Wall) Footings – Used under bearing walls or strip foundations.
- Deck Footings – Configurable using the deck footing calculator for load path and bearing area checks.
- Embedded Post Footings – Analyze depth, embedment, and post-bending strength using the embedded post calculator.
Custom options allow for varying soil capacities, post sizes, and loading conditions.
What Loads and Soil Properties Must Be Considered?
Proper footing and post analysis accounts for:
- Axial Loads – Dead and live loads transmitted from above.
- Lateral Loads – Wind or seismic forces requiring sliding and overturning checks.
- Moment Loads – Especially at embedded posts and eccentrically loaded footings.
- Soil Bearing Capacity – Input allowable bearing pressure based on geotechnical reports.
- Frost Depth and Embedment – Account for local climate and uplift resistance.
StruCalc’s calculators incorporate these values to ensure safe and efficient foundation design.
How Does StruCalc Assist with Concrete and Deck Footings?
Using the concrete footing calculator or deck footing calculator, engineers can:
- Evaluate soil pressure under different footing shapes and sizes.
- Automatically apply load combinations per IBC and ASCE 7.
- Determine required footing dimensions for axial and moment loads.
- Check uplift and overturning resistance for freestanding and attached decks.
Calculations follow standard design methods for both residential and light commercial applications.
What is Included in the Embedded Post Calculator?
Embedded posts are common in fences, decks, and post-frame buildings. StruCalc’s embedded post calculator includes:
- Analysis of bending strength, embedment depth, and soil resistance.
- Checks for rotation, pull-out, and bearing failure.
- Options for wood, steel, or composite posts.
- Support for load combinations and unbraced length.
This makes it easy to verify post safety under multiple real-world conditions.
What Codes and Standards Does StruCalc Support?
StruCalc’s footing and post modules follow:
- IBC (International Building Code) – Governs load combinations, frost depth, and minimum bearing.
- ACI 318 – Concrete design specifications for isolated and wall footings.
- NDS – Wood post design including axial and bending interaction.
- ASCE 7 – Prescribes dead, live, wind, and seismic loads.
All calculations can be reviewed, printed, and submitted with permit drawings.
Why Use StruCalc Instead of a Manual or Spreadsheet-Based Footing Calculator?
Spreadsheets are limited when it comes to handling real-time loading conditions, post-bending interactions, and linked reactions from framing systems. StruCalc offers:
- Integrated Load Path Tracking – From roof to soil.
- Automatic Footing Sizing – Based on loads and allowable soil pressure.
- Custom Post Embedment Analysis – With rotation and uplift checks.
Permit-Ready Outputs – Clear documentation for building officials.
