Basic Design & Engineering Chapter 2 of 10 Basic Design & Engineering Presented by: Al Cobb, Founder, Sips School www.sipschool.com SPONSORED by: Chapter 1- Introduction to SIPs

Learning Objectives Look at industry standard details Recognize SIP-friendly architectural styles Understand the many decisions that make up panel design Review basic engineering concepts as it relates to panel design These objectives should be a precursor to the start of the first hour of training?? I would think they would be a part of the course description and not associated with the video shoot. Chapter 1- Introduction to SIPs

Architect or Designer? Architect Designer Creates custom design based on input Designer Stock plan adjustments Permit drawings

Design Considerations Do the construction drawings “need” to be designed for SIPs? Does a structural engineer “need” to review the SIP shop drawings? Are roof SIPs the best choice? Know when to say NO

SIP Design (CAD) Not to be confused with architectural design Typically converting stick framing to SIPs 2D & 3D Computer Aided Drafting/Design (CAD) AutoCAD is the dominate program (taught in schools) Other programs are available Panel specific – hsbCAD, Dietrich, cadwork Architectural programs - ArchiCAD, SoftPlan, Chief Architect, etc. 3D CAD can solve building design flaws early - virtual reality CAD provides seamless transfer to CNC fabrication

CAD/CAM SIP software converts SIP CAD drawings into machine instructional code. SIP drawings are usually done in AutoCAD or architectural desktop (ADT). SIP software converts these drawings into machine instructional code. Not all manufacturers use CAD/CAM technology, but the industry is moving in this direction.

SIP Design A good SIP designer balances the needs of the engineer, the budget, and the installer Good SIP design drawings relay all critical information related to the installation of the SIPs Buildings are built from the ground up, but should be designed from the roof down.

What decisions does a SIP designer make? Where SIPs should be used What thicknesses and sizes are appropriate How the roof SIPs are supported Where headers are required That point loads are addressed That tall walls have sufficient stiffness Spacing of nails and screws Whether an opening is cut from a SIP or it is pieced together

Wall SIPs What determines thickness? R-value Height vs. lateral load Energy modeling

Headers Where are headers required? How wide is the opening? What is above the opening? How much SIP is above and on each side of the opening? Use a SIP header or a built-up header? Transfer of gravity and point loads.

Headers SIP headers can be used when there is at least 12-inches above and on each side of the opening and the width and load over the opening is within the design parameters Detail courtesy of Premier Building Systems

Headers Built-up headers are used when the width of the opening or the load over the opening exceeds the design parameters for using a SIP header, or when the height above or on each side of the opening is less than 12”. Detail courtesy of Premier Building Systems

Point Loads How are the point loads being handled? Posts in the walls Extra top plates SIPs handle load via both skins

Load Transfer – Two Strategies

Lateral forces on walls (Wind) Chapter 1- Introduction to SIPs

Tall Walls Are the tall walls going to move in a strong wind Tall walls are defined as greater than 12’ high up to 110 mpg or greater than 10’ high at 120+ mph EWP vertical stiffeners? Steel?
