AI-Assisted Computational Modelling Workflow for Structural Analysis of Old Masonry Buildings
Bora Pulatsu
Session 2
No. 1
8:25 – 8:45 AM
Deterioration in masonry infrastructures and cultural heritage is inevitable due to environmental factors and extreme loading conditions. However, with the implementation of cost-effective preventive maintenance, structural health monitoring and the application of robust computational modelling techniques for structural analysis and safety assessment, it is possible to conserve rapidly aging unreinforced brickwork and stone masonry buildings.
The present study aims to offer an innovative workflow for the structural analysis of unreinforced masonry (URM) buildings by utilizing recent advances in computer vision techniques to create discontinuum-based computational models. The adopted modelling approach represents load-bearing masonry elements as a system of rigid blocks interacting with each other along their boundaries based on the point-contact hypothesis. At each point-contact among the adjacent blocks, bond behaviour is simulated through cohesive constitutive law in tension and shear, while the phenomenological response of masonry composite is considered in compression. A special attention is given to the accurate representation of masonry construction technique and morphological features of masonry walls within the proposed modelling strategy. To this end, a novel data-driven structural analysis workflow is proposed in which artificial intelligence (AI)-assisted visual inspection is utilized for object identification and classification using vision-based resources such as images, videos, and live feeds. The system is powered by an object detection model trained from a dataset containing a collection of sample images with manually created annotations serving as ground truth data. A trained object detection model is used to identify objects of interest and perform instance classification.
Through this process, important inferences are made regarding the masonry unit size distribution, bond pattern, and masonry quality index parameters that are directly used in the generation of the computational model, which is later utilized for nonlinear structural analysis.
Furthermore, the results of the advanced computational models are compared with the standard macro-block analysis adopting the upper-bound theorem of limit state analysis that is commonly used in practice. The proposed workflow for advanced structural simulation of masonry buildings is tested on a two-storey stone masonry building. The outcomes highlight that the proposed data-driven structural analysis workflow enhances the capabilities of the up-to-date computational models and offers accurate predictions regarding the structural performance and capacity of analyzed URM buildings, which prevents the execution of unnecessary intervention plans or irreversible strengthening solutions.

Saving a Main Street Building
Craig Bennett, Jr., PE, SE, RP APT
Session 2
No. 2
8:45 – 9:05 AM
Not all old brick masonry buildings are National Historic Landmarks, not all are on the National Register, and not all are even in historic districts. But Main Street in every older town and city in the nation is filled with unreinforced brick masonry buildings. Some are in great shape, and are now occupied by Walgreens, Apple, Victoria’s Secret, Gap, and Starbucks. But some are not.
One rather ordinary 1890s brick masonry Main Street building in Greensboro, North Carolina was in exceptionally poor shape, neglected and passed over for renovation, primarily because it was on an exceptionally challenging site, with railroad tracks on two of its four sides. In this brief talk, Craig Bennett reviews the challenges of dealing with a severely deteriorated building on a tight site, in a zone of moderate seismicity, and shows how incredibly resilient brick masonry buildings can be.
Craig Bennett is the founder and president of Bennett Preservation Engineering PC. He is a structural engineer with undergraduate degrees in both civil engineering and architecture, and a graduate degree in structural engineering. For the past 34 years, his focus has been on structural engineering for historic structures, particularly historic masonry structures.

He is currently adjunct faculty in the Clemson University Graduate Program in Historic Preservation, is active in building code development in The Masonry Society, is past president of the Board of Trustees of the Charleston Museum and past chairman of the City of Charleston’s Board of Architectural Review.
Washington National Cathedral – Seismic Strengthening of Limestone Turret
Matthew Farmer, PE
Session 2
No. 3
9:05 – 9:25 AM
As a result of the Mineral, Virginia earthquake on August 23, 2011 the Washington National Cathedral sustained some of the most significant, visually striking, and potentially dangerous damage. The Cathedral, whose construction began in 1897, is an unreinforced stone masonry structure in the Gothic Revival style characterized by an abundance of flying buttresses and of carved stone cantilevered spires and pinnacles at various elevations over its 300 foot height. A number of these elements partially collapsed during the earthquake and many more shifted position.
Given the magnitude and complexity of the Cathedral structure, simple and direct seismic assessment approaches were needed to: evaluate the dynamic characteristics of the types of elements that were damaged and measure the reliable existing capacity of these elements They also enabled development of targeted repairs to vulnerable ornamental elements that are “tuned” to their risk of future instability. This presentation will highlight the most recent innovations is seismic strengthening used at the Cathedral to date.
Mr. Farmer joined the New Jersey office of WJE in 1986 and moved to the Washington, DC office in 1990. He serves as principal investigator on evaluations of concrete, steel, and timber structures, as well as clay, concrete, stone, and cast stone masonry. He concentrates his practice in building enclosure systems engineering, design, investigation, analysis, and repair.

Existing Masonry Draft Pre-Standard: What it says, what it does not say, and how to use it
Heather Sustersic, PE
Session 2
No. 4
9:25 – 9:45 AM
TMS 402/602, Building Code Requirements for Masonry Structures, applies only to new construction. The United States and Canada currently do not have a referenced standard dedicated to existing masonry that can be adopted by an Authority Having Jurisdiction, except for seismic-specific applications covered by ASCE 41. The Existing Masonry Guidelines (EMG) Task Group of the TMS Existing Masonry Committee has been working to change that over the past 3 years.
As part of a 5-year plan and in cooperation with Canada Masonry Design Centre, TMS held a technical Summit in March, 2024, to write a first draft of a pre-standard document for existing masonry. Modeled after American Concrete Institute (ACI) 562 for concrete, Code Requirements for Assessment, Repair, and Rehabilitation of Existing Concrete Structures, the draft pre-standard is ready to hand over to the Existing Masonry Committee during the Fall, 2024, TMS meetings for formal balloting.
This presentation provides a summary of the background and coordinated approach applied in writing the draft pre-standard and an update to the masonry industry at large regarding its trajectory. We will present a high-level overview of what is included in each chapter, what is specifically excluded and why, and how the document is intended to be used by design professionals and code officials.
Mrs. Sustersic, P.E., is a practicing structural engineer with Colby Company Engineering in Portland, Maine, experienced in the design of new buildings, complex renovations, sculptures, and specialty engineering projects, as well as performing condition assessments of existing building structures for commercial and federal clients.

Differential Movement – Beware The Backup Structure
Peter Babaian, PE, SE
Session 3
No. 1
10:10 – 10:30 AM
A recent trend in low-rise multifamily construction includes multiple stories of wood framing over a concrete podium structure or slab. Many buildings feature brick masonry exterior cladding systems to meet zoning ordinances, match aesthetics of the surrounding area, or project an upscale image. The combination of brick veneer over wood framing, if not appropriately detailed and thought through, can lead to poor results and significant rework due to differential movement. This presentation will review the movement compatibility issues between wood framing and brick masonry and explore ways to prevent issues from occurring on future projects by looking at past failures.

Dry-Cast Low Carbon Concrete Masonry Units
Heidi Jandris, BARCH, MSSBS, WbLCA-P
Session 3
No. 3
10:50 – 11:10 AM
This course aims to help designers understand why concrete sequesters carbon dioxide by first looking at the larger geologic carbon cycle and then the cement production carbon cycle. It also discusses the differences between dry-cast (CMU) and wet-cast (ready-mix/pre-precast) concrete and how these differences contribute to CMU assemblies having lower embodied carbon and increased carbon sequestration rates. Mini embodied carbon cradle to gate Life Cycle Analysis (LCA) studies are compared for several types of wall assemblies and will look at additional strategies to lower embodied carbon during the manufacturing and use phase, including raw materials, efficient design, utilizing thermal mass, durability, resilience and End Of Life (EOL) carbon sequestration.

Towards an Improved Understanding of Partially Grouted Shear Walls
Carlos Cruz-Noguez, PhD, PEng
Session 4
No. 3
11:55 AM – 12:15 PM
Due to its economy and efficiency, most masonry walls in low- to moderate-seismic regions are built with partially grouted (PG) masonry. Designing a PG shear wall is complex due to the heterogeneous nature of masonry, the distinct nonlinear behaviour of each component in the assemblage (masonry unit, mortar, grout, reinforcement, etc.), and the interactions existing between solid and void spaces in the wall. As a result, current North American design provisions for masonry structures (CSA S304-14 and TMS 402/602-22) are limited in their ability to predict the diagonal tension shear capacity of partially-grouted walls with consistent accuracy. Particularly concerning is the increasing number of research studies reporting that North American design provisions tend to significantly over-estimate the shear strength of partially-grouted walls and predict behaviour inconsistent with experimental studies involving partially-grouted walls. This presentation covers the historical developments of shear equations for PG walls and recent progress made through advanced statistical analyses, experimental studies, and finite-element models in which new insights have been gleaned in our work towards safer and more economical design methods.
