1/27/21 Resiliency – Consideration Beyond Code Requirements Shamim Rashid-Sumar, PE, FSFPE (National Ready Mixed Concrete Association) 1 Hour

Part of the Sustainable Structures Webinar Series
View Description

---Close---

Part of the Sustainable Structures Webinar Series: Prescriptive building code requirements represent provisions for the least safe structure that may legally be built in a jurisdiction. Over the past 20 years, the building design and construction industry have witnessed an increase in the number of trade-offs of passive fire safety features for active systems. As natural disasters attributed to climate change continue to escalate, the population of neighborhoods located along with the wildland-urban interface increases, and fire and emergency access to buildings in densely populated areas is obstructed, multiple drivers arise to consider more robust construction for our built environment.

The presentation will provide an overview of increased risks from natural and human hazards, identify approaches to mitigate their effects through voluntary and mandatory strategies and demonstrate the importance of incorporating standards for resiliency beyond minimum code requirements.

View Description

---Close---

There are five commonly used procedures for designing industrial floor slabs. All of them are effective when their recommendations and details are followed. So, how does a designer choose the best method for a particular floor?  The most common approach is to determine the type of floor construction needed for expected loading conditions. Then, from the design procedures, select the most appropriate method for determining floor thickness, reinforcement, joint spacing, and other details.  This presentation will discuss the ACI 360 “Guide to Design of Slabs on Ground”.  It will briefly address the planning, design, and detailing of slabs. Background information on design theories is followed by discussion of the types of slabs, soil-support systems, loadings, and jointing. Some worked design examples for various types of concrete slabs-on-ground will also be covered.

Concrete is the foundation for everything we build. Concrete is an integral part of homes, businesses, schools, offices, churches, roads, and bridges. The concrete industry is in need of people who aren't afraid of hard work. A career in the concrete industry not only pays well but gives individuals the chance to build something that will stand the test of time. Right now, there is a growing need for concrete contractors, equipment operators, ready mix concrete truck drivers and quality control personnel. #ConcreteTough is a Nebraska based workforce recruitment campaign that exposes youth to the concrete construction industry. This message is communicated through participating in various career fairs, concrete 101 programs, and presented to numerous schools on the different careers the concrete Industry offers. Attendees will learn ways that they can incorporate concrete career awareness into their own workforce recruitment efforts.

A short overview of the new Concrete Industry Management degree at South Dakota State University will also be included with this webinar.

View Description

---Close---

Mass concrete (or thermally controlled concrete) typically requires implementing thermal control measures to reduce maximum temperature and mitigate temperature difference. Specified temperature limits and thermal control requirements can affect mix design proportions, materials selection, reinforcement details, construction operations and compliance to specifications for the work. Many specifications still limit concrete temperatures to overly conservative default values without recognizing concrete properties and performance that allow alternative temperature limits more suitable for the specified work while maintaining quality and improving constructability. This issue frequently results in challenging scenarios that create design difficulties and unnecessary constructability problems for mass concrete. This presentation focuses on the implementation of today’s knowledge of mass concrete and best practices to overcome mass concrete challenges and facilitate solutions in projects. A special emphasis will be given to the technical updates provided for mass concrete requirements and guidance progressing in North America industry standards.

Concrete is unique among building materials. Its formulation is highly influenced by its application. Design professionals and contractors have a greater influence on concrete formulation than they do with other building products. Concrete can be made stronger, lighter, more flowable, stiffer, less permeable, and even weaker depending on performance needs. No other building material is that versatile. This presentation will discuss how design and construction teams can implement ten simple strategies to reduce concrete’s carbon footprint today. The recommendations are listed broadly in order of priority, but not in order of impact reduction. All are important and should be implemented. In addition, the strategies are meant to achieve a lower carbon footprint without impacting other desired performance capabilities for the concrete.

Part of the Sustainable Structures Webinar Series: Look around and you’ll see many five to seven story projects being built today with a one- or two-story concrete pedestal, supporting up to five floors of steel or wood frame. These “pedestal” projects are assumed to be the cheapest way to build while longer term ownership implications of these designs are not well understood. This one-hour presentation dispels the myths that are driving the popularity of pedestal construction and demonstrates the value concrete provides.

 

The developer/owner’s perspective on building multi-family housing projects with Insulating Concrete Forms (ICFs) will be presented, and will include design, construction, and energy-efficiency implications, as well as tenant satisfaction. The presenter will overview his use of ICF’s and concrete for the exterior wall system at Kendal Lofts, a 42-unit project in Waukesha, Wisconsin. In addition, the presenter will also discuss his latest all-concrete residential projects in Wisconsin and Florida.

Anyone who has watched a building under construction can appreciate its complexity and sophistication. Occasionally, inspection and testing requirements occur that the local code official may not be qualified or experienced to address, so third-party assistance is needed. The building codes address this need through a specific requirement for structural tests and “special” inspections. A special inspection can be required for materials, installation, fabrication, erection or placement of components and connections where special expertise is needed.  This presentation will cover the requirement of special inspections as well as some examples of when construction testing and inspections did not go as planned.
