Strengthening of Concrete and Masonry Structures using Externally Bonded Fabric Reinforced Cementitious Matrix (FRCM)

Fabric Reinforced Cementitious Matrix (FRCM) is a new and innovative composite material, which provides unique advantages to traditional Fiber Reinforced Polymer (FRP) composites.  

This presentation will provide an overview of FRCM and address important considerations including applicable codes and standards, material properties, installation, qualification testing, quality assurance, field & lab testing, and key governing limits when designing with FRCM.

Nishan Pethiyagoda

Nishan holds a bachelor’s degree in Architectural Engineering and a master’s degree in Civil Engineering from the University of Texas at Austin.

Deck Connections and the Factors that Affect Performance

The structural community specifies roof and floor deck connections as traditional arc spot puddle welds, screw fasteners, or mechanical fasteners. This presentation will identify the limitations of deck connection types and will bring awareness to the most consistent and reliable fastening approach.

Braced Frame Adaptations for Speed and Height

The fast delivery schedule of the 19-story office building at 145 Broadway in Cambridge, MA directed the need for an up-down construction scheme with steel braced frames.  Coordination with the contractor, fabricator and erector helped execute supplemental solutions in steel plate shear walls and composite columns on the schedule of a traditional braced frame.

Michael Murphy, AIA

Structural Steel: The Unsung Hero at Wrightwood659

The new Wrightwood659 Art Gallery in Lincoln Park has received much press since its Grand Opening in the fall of 2018 boasting an atrium of salvaged brick and glistening concrete by world famous architect Tadao Ando. However, hidden behind the amazing photos of Ando Concrete and incredible interiors are several STRUCTURAL STEEL frames inserted within the existing wood framed building prior to its demolition. The steel frames, now forever cast in concrete, have a story to tell and secrets to reveal helpful to all structural engineers.

Matthew Wagner, SE

Matt Wagner, S.E. is a Senior Project Engineer at Raths, Raths & Johnson, Inc., an Illinois-based national engineering, architecture, and forensics consulting firm specializing in the investigation, design, repair, and testing of building structures, enclosures, and materials.

Structural Analysis for a Portal Frame Building with Material Uncertainty
The material and geometrical properties of an existing building change throughout its lifespan. Therefore, quantification of those properties is uncertain when determining its structural response. In this work, structural analysis on two portal frames of an existing building with uncertainty in their material properties is performed. The analysis results show that this method, due to consideration of uncertainties, can be used for decision making on the need for the repair, retrofit and rehabilitations of existing buildings. 

Steve Zimmerman

Steve Zimmerman is Unit Manager and Associate Principal in WJE's Structural Testing and Instrumentation group in Northbrook, IL.  Mr. Zimmerman joined WJE in 2001 and has since been involved in projects investigating wood, steel, and concrete structures as well as laboratory and field testing of construction materials and structural systems.  Assignments have included field investigation, assessment, analysis, and repair design of existing structures.

Building the Future — Challenges of Designing with New Materials

As new construction materials get introduced to the market it is important that engineers become familiar with factors beyond just the mechanical properties associated with those materials as part of the evaluation process.   Items that should be considered include long term performance characteristics, environmental exposure and interaction, and also whether the material behavior is consistent with the basis of design for existing codes.

Jennifer Anna Pazdon, PE and Ka Lung Ng, PE, SE, CPEng

Ms Pazdon is a licensed structural engineer in NY with over 13 years of experience in design of structures. She received her Bachelors from Carnegie Mellon University and her Masters from Princeton University where her studies focused on aesthetics, efficiency, and economy in structural design.

Innovations in Cast Steel: The Chicago Transit Authority Belmont Station Canopy

The rehabilitation of the Chicago Transit Authority’s Belmont Station on the O’Hare line features the addition of a soaring, curving, cantilevered canopy. Three columns support a glass roof structure that cantilevers nearly 60 ft to the front and 30 ft to the rear. The cantilevers are composed of architecturally exposed loops of continuously tapering, built-up rectangular hollow steel sections. 

 Benton Johnson, PE, SE

Benton Johnson is a senior structural engineer at Skidmore, Owings & Merrill LLP in Chicago. He has been with SOM for 12 years working on a broad range of international and domestic projects. His work also includes research projects and experimental buildings constructed with additive manufacturing (3D printing). 

3D Printed Concrete – Barracks Hut Case Study

Additive manufacturing (3D printing) is a rapidly expanding field with applications in prototyping, product manufacturing, and the building industry. Several recent demonstration buildings have been recently completed, including two barracks-huts (B-Huts) constructed at the Construction Engineering Research Laboratory (CERL) at the US Army Corps of Engineers’ facility in Champaign, Illinois. Skidmore, Owings & Merrill LLP (SOM) assisted CERL in the design of their second B-Hut, which was designed to meet the intent of building codes. This presentation will review the design of the second B-Hut and the challenges of 3D printed concrete materials. 


Rigid Origami Kinematic Surface

The MAK Center Pavilion is the world's first large-scale, kinematic, rigid origami structure. Constructed from flat panels, the shape allows the pavilion surface to move and flex in a specific motion with the application of minimal force. The structure was a result of numerous firm-wide structural engineering and architectural research initiatives.
