Engineering Tiki Huts in Florida: Tribal Exemption Limits and Code-Compliant Design

Engineering Tiki Huts in Florida: Tribal Exemption Limits and Code-Compliant Design Florida recognizes an exemption allowing Native American tribes—primarily the Seminole Tribe—to construct traditional chickee or tiki huts without full compliance with the Florida Building Code (FBC) when built on tribal lands. This exemption exists due to tribal sovereignty and cultural preservation of traditional building methods. Structural …

How To Calculate Porosity of a Louver – Sign – Fence Per ASCE 7

Porosity – How ‘Open’ A Surface Is – Explained The porosity of open structures is defined in ASCE-7 standard under ‘open signs’ (chapter 29, as of ASCE 7-22). This standard explains that the permeable (wind) porosity of a surface isn’t always equivalent to the calculated visual porosity. Left: mechanically articulating louvers that can reach a …

ASCE 7 Main Wind Force vs. Components & Cladding Explained (MWFRS vs. C&C)

ASCE 7 separates wind loading into three types: Main Wind Force Resisting System (MWFRS), Components and Cladding (C&C), and Other Structures and Building Appurtenances. MWFRS is defined as “(a)n assemblage of structural elements to provide support and stability for the overall structure.” Typically, members that receive loading from two surfaces are designed to resist MWFRS …

ASD vs LRFD Explained

Should a professional utilize the ASD (Allowable Stress Design) method or the LRFD (Load Resistance Factored Design) method when calculating the required wind pressure for use with tested-approved systems?

What’s The Difference Between ASD & LRFD Design? Put in layman’s terms, think of a wood plank designed to stretch between two supports. You’re going to walk across the piece of wood. The person that designed that plank needed to figure out if it will hold you. They had two options when designing: 1) Reduce …
