What Building Professionals Need to Know About Construction Loading

This week’s post was written by Shawn Overholtzer, ICS Business Manager
at Simpson Strong-Tie. 

Understanding construction loading is important as it relates to the acceptable practices in terms of staging and storing construction materials prior to installation. What does “construction loading” mean? This term describes materials and people that are present during the course of construction. It refers to any construction material that is stacked and/or staged on the trusses for any length of time prior to the installation of said materials. This also includes those individuals that are working or walking on the trusses during the course of construction.

One of the most important concepts to understand is that before any construction materials can be loaded on roof or floor trusses, the trusses must be adequately restrained and braced. This must be done in accordance with BCSI-B1 and BCSI-B2. Loading material on trusses prior to adequate restraint and bracing can lead to failure, collapses, injury and even death. This is especially important when structural elements such as roof or floor trusses are involved.

Good Ideas Come from Many Places — “Necessity Is the Mother of Invention”

You never know where the next great product idea or innovation is going to come from — some of our best new ideas originate with the customers who use our current products. At Simpson Strong-Tie, we welcome any inspiration that can help us serve our customers’ needs even better. With so much competition, however, and because so much research and testing are entailed in developing each new product, the criteria that an idea must meet to gain eventual acceptance are necessarily quite rigorous. In this post, Steve Rotzin, Manager of Intellectual Property and Legal Services at Simpson Strong-Tie, outlines some of these criteria for your consideration.

All of us, at one time or another, dream up a product idea of some sort. My wife was once sanding the tongue-and-groove boards of our living room ceiling and she thought of a very cool idea of gloves that had Velcro on them and users could interchange sandpaper of various grit on any finger of the glove. If you’ve ever sanded anything, this actually made a lot of sense especially for complex shapes and tough to reach spots. I researched it and found out that someone had already thought of it and “patented it.”

What You Should Know About the New DGH Fire Wall Hanger Options

Does everyone do year-end performance reviews to discuss how you did on your project objectives and professional development goals? I love meeting with my team to recap all their amazing accomplishments for the past year, discussing long-term career plans and figuring out the steps we will take to implement those plans over the next six months, year, and beyond. I hate, hate, hate, hate doing all the paperwork that HR requires – but I am done with it now, so I’ll get over it.

One of our new product objectives for 2017 was to create a new fire wall hanger that could be installed before the drywall. Creating a joist hanger that can span a gap while still meeting the target loads was a challenging task. We released the DG series of fire wall hangers in July. I discussed the use of fire wall hangers in Why Fire-Rated Hangers Are Required in Type III Wood-Frame Buildings.

New CSS Product Launch — FRCM Strengthening Products

The new FRCM Composite Strengthening Systems™ repair and reinforcement solution from Simpson Strong-Tie combines high-performance sprayable mortar with a carbon-fiber grid that creates a thin structural layer that repairs and strengthens without significantly increasing the structure’s weight or volume. FRCM stands for fabric-reinforced cementitious matrix. Its advantages are similar to those of FRP (that is, strength, low weight and ease of application), but it may also be used to repair, resurface, strengthen and protect in one application, along with providing greater resistance to heat and better long-term durability.

How Computer Simulation Can Power Innovation

This week’s post was written by Frank Ding, Engineering Analysis & Technical Computing Manager at Simpson Strong-Tie. 

Computer-simulated product testing is being used increasingly in modern engineering and manufacturing because it provides a low-risk, time- and cost-efficient means of modeling system performance using a wide array of variables before a physical prototype has been created. The following Blog post outlines some of the uses and advantages of integrating this technology into the product development process.

The role of test simulation in product design might not be the general focus of the Structural Engineering Blog. However, you may have noticed that computer simulation plots have been cited in a few previous postings. Nowadays, it’s rare to talk about product development without mentioning computer simulation at some point. The aim of this post is to give you a better sense of how test simulation can benefit product development and innovation.

My Engineering Adventures with Build Change

This week’s post was written by James P. Mwangi, Ph.D., P.E., S.E. – our first annual Simpson Strong-Tie Engineering Excellence Fellow with Build Change. 

Let me start by wishing everyone a happy holiday season.

My fellowship activities started in July 2017. I spent two weeks in New Jersey getting oriented to the Build Change organization and engineering activities around the world. I then spent two days in Pleasanton getting to meet the engineering team and getting updated on Simpson Strong-Tie products and the team leaders.

Simplify Access to Your Drawings with the Simpson Strong-Tie AutoCAD® Plugin

This week’s post was written by Carolyn O’Hearn, Software and App Marketing Manager at Simpson Strong-Tie.

Accessing engineering drawings, determining whether you have the right ones and loading them into AutoCAD can seem like an exhausting endeavor. Wouldn’t it be nice to have an application that does everything you need in one package? An application that will also save you time, on both retrieval and installation, and give you access to additional applications? Simpson Strong-Tie has developed a new tool that can take care of all these needs.

Turkeys and Gratitude

This week’s post was written by Kari Martin, Marketing Communications Content Manager at Simpson Strong-Tie. 

There are a couple of turkeys that like to hang out around our home office in Pleasanton and, no, I’m not referring to any of my colleagues — we actually have a gang of wild turkeys that comes up from the creek behind the office. Almost every day, these colorful birds feel safe enough to stroll onto the office walkway pecking for food outside our office windows and doors. It’s surprising to me that these beautiful creatures could be so fearless (or is it simply naïve?), especially around Thanksgiving time. Their presence reminds me that being fearless is important, because nothing new would ever be discovered if we were too afraid to venture outside our comfort zones.

The beauty and strangeness of the turkeys also remind me to be thankful, because everything we have in life is ultimately a gift. Their consistent return to our office is a gentle reminder as I walk into work to give thanks to you, our readers, our customers and our partners every day. Thank you!

We hope you enjoy the holiday with your family and friends. We’ll be back with another post next week.

A New Way to See Whether FRP Is Right for Your Project

This week’s post was written by Griff Shapack, FRP Design Engineer at Simpson Strong-Tie. 

Specifying our Composite Strengthening Systems™ (CSS) is unlike choosing any other product we offer. In light of the unique variables involved with selecting and using fiber-reinforced polymer (FRP) solutions, we encourage you to leverage our expertise to help with your FRP strengthening designs. To get started, we first need to determine whether FRP is right for your project. The fastest way to do that is for you to fill out our Design Questionnaire. Our new Excel-based questionnaire collects your project information and helps you use the existing capacity check to evaluate whether or not FRP is suitable for your project per the requirements of ACI 562-16 Section 5.5.2. After the feasibility study, the questionnaire creates input sheets specifically for your project.

AC398 Now Includes Moment Evaluation of Cast-in-Place Post Bases

This week’s post was written by Jhalak Vasavada, Research & Development Engineer at Simpson Strong-Tie.

When we launched our new, patent-pending MPBZ moment post base earlier this year, the evaluation of the moment capacity of post bases was not covered by AC398 – or by any other code, for that matter. There wasn’t a need – there were no code-accepted connectors available on the market for resisting moment loads.
