Brick, Block & Beers: Vol II Issue II- Masonry Best Practices: Control Joints for Concrete Masonry walls

7/30/2018

Picture
The pictures provided show cracks under the precast header bearing at what appears to be both ends of an opening. These cracks then turn and extend up to the top of the wall through the course above the precast in a stair step fashion. The third picture provided shows cracking under the end of a precast sill which then extends from the lower right hand corner of the opening down the wall in a stair step fashion.
 
 My response to this inquiry is based strictly on the 3 pictures provided. There may be other extenuating circumstances that I am not aware of.
 
 The pictures provided are so indicative of classic masonry shrinkage cracking that I intend to catalog and use them in future presentations to show where cracking usually shows up in structures where shrinkage of the masonry has not been addressed by either horizontal reinforcing or properly placed control joints.

There are three important considerations to keep in mind when working with either concrete or concrete masonry - it's gray, it gets hard AND IT CRACKS. The cracking can be caused by movement (such as foundation failure), expansion and contraction due to temperature differential or drying shrinkage. Of these three, drying shrinkage is the by far and way the most common and MUST be addressed if random cracking is to be prevented. Concrete materials shrink when they loose moisture. Concrete poured under water does not

Masonry Wall Design: Single-Wythe
Moisture penetration through exterior walls is a concern on every project (or – it should be a concern on every project!). Single-wythe concrete block construction does a great job in preventing water from entering the interior of your building but there are several important “belts and suspenders” that should be included in your design to make sure your masonry wall does the best job possible.

So, what do we consider a single-wythe wall? There are three major types of masonry walls built in Florida.  The very best masonry wall to prevent water passage (we call it The World’s Best Wall!!) is called a double-wythe cavity wall and contains a drainage/air space between two separate wythes or “layers” of masonry.  Water that makes it through the first wythe runs down the back side of the wall and is discharged to the exterior through flashing and weeps.

MASONRY CONSTRUCTION & INSPECTION WORKSHOP
Updated for 2016 TMS 402/602, ASTM Standards and the
​6th Edition of the Florida Building Code!

Whether designing, building, testing or inspecting, when you’re working with masonry, understanding all of the codes and specifications governing the various masonry components (block, brick, grout, mortar and steel) is essential.
Understanding the role of each of the team players involved with a masonry project is imperative. That’s why this one-of-a-kind workshop was developed. Unique in its big-picture approach to masonry it offers the latest information on all aspects of Design, Workmanship and Materials. Members from the entire masonry family, from building inspectors and architects to masons and engineers, are in attendance at each class. The course instructors are 5 distinguished members of our industry each with a lifetime of “on the job” experience. Instructors present both basic and up-to-date issues in their field while focusing on how each discipline works with the others to ensure quality masonry.

NEW CODES & STANDARDS
Workshop covers all the new codes and standards used in masonry: 2016 TMS 402/602 (Formally ACI 530/530.1); Updated ASTM Standards referenced by the 6th Edition Florida Building Code; Updated BIA and NCMA Tech Notes; changes to the Florida 6th Edition masonry chapter and much more!

Masonry Testing Protocols
HAPPY NEW YEAR!!! I hope everyone had a great 2017. I am believing that it will be a better than ever year for the masonry industry in 2018. As I began to think about starting a new year, I looked at it similar to starting a new building project. As you review the specifications for the materials you will submit for approval you see the section on quality assurance. If it is a small project you will probably take care of it with paper work in your submittal. But if the project is a large project, it will probably include onsite testing. Serious thought and planning should be put into the testing procedures to be used. Chapter 3 of the TMS 402 Code says that “Masonry design requirements in this Code are valid when the quality of the masonry construction meets or exceeds that described in the Specification.” The designer will set up the QA (Quality Assurance) Program based on one of three requirement levels. The program will also describe the procedure for reporting and review as well as resolution of non-compliance. The QA Program will also state the qualifications of the testing laboratory and inspection provider. You will notice the last three sentences had mandatory language, such as “will” in them. This is not optional. If this is not provided, you should...

Why does masonry perform so much better than other light frame products during high-wind events, such as hurricanes and tornadoes?
​

Picture
Masonry's Greatest Strength
Long time South Florida residents who have weathered a severe hurricane often express a heartfelt thankfulness that they were in a concrete masonry structure. Structures built of many lesser products have weathered hurricanes but block homes provide the secure comfort of rock solid construction. This is not just antidotal – its common sense. After reading this article perhaps you will have a better understanding of concrete masonry’s built in strength.

It’s all about the “safety factor”. Simply stated the “safety factor” is the difference between what engineers expect will be the largest wind load a structure will ever be exposed to --- and the wind load that they calculate would rip the structure apart. Structural engineers always like a good safety factor – usually around 3 times or 300%. Poor construction and material deficiencies erode safety factors but if you have sufficient safety factor there is some room for error.

Understanding Wood Frame Connection Problems
Wood frame residential structures have performed poorly in every wind event I have had the opportunity to do wind damage assessment on. The problem is not in the wood itself but in the connectors. A tree branch can be very strong – but if you saw it off you will have a real problem on your hands to nail it back on to its original strength.
The lumber industry is extremely sophisticated in their design procedures. Nails and connections are assigned industry accepted load carrying capacities and safety factors based on extensive testing. All of this is proper engineering. There is, however, a number of factors which explain why Hurricane Irma left dozens of modern wood structures in ruins and zero concrete masonry structures in ruins.

These are:
  • Product Weight and Stability
  • Natural Safety Factors in Design
  • Complexity in Design
  • Complexity in Connections
