Although UMass Dartmouth's Science and Engineering Building has long been viewed as an architectural treasure, its aging interior and structure have presented some challenges to users nearly 50 years after it opened. This talk examines Ellenzweig's extensive retrofitting of the UMass Dartmouth SENG building for accessibility, a new envelope, updated MEP, and fire-safety measures. After looking at the design phase and interactions with the Mass Historic Commission, the talk ends with an examination of the replacement of windows in the building.


Concrete Deterioration And Diagnosis, Matthew B. Bronski 2021 Simpson Gumpertz & Heger

Concrete Deterioration And Diagnosis, Matthew B. Bronski

UMassBRUT Community

Built primarily in the 1960’s, mid-century modernist concrete buildings are now at the age when we regard many as historic or architecturally significant (and thus as deserving of careful restoration and stewardship), but also at an age where many now exhibit significant deterioration. In this presentation, Matthew Bronski describes the most common maladies and deterioration mechanisms that can befall exposed concrete facades, outlines investigative and diagnostic approaches, and discuss the pros and cons of different rehabilitation treatment options, and the importance of tailoring the treatment to the malady.


Brutalist Structures – Polychlorinated Biphenyls, Theresa Wolejko 2021 University of Massachusetts Amherst

Brutalist Structures – Polychlorinated Biphenyls, Theresa Wolejko

UMassBRUT Community

Until they were banned by the Federal Government in 1978, Polychlorinated Biphenyls or PCBs, were used extensively as sealants in Brutalist structures across the United States. As a result, these hazardous chemical compounds still reside in concrete buildings and present a danger to those looking to clean or renovate Brutalist structures. This talk explains the problems the University of Massachusetts Amherst has faced in dealing with PCBs over the last couple of decades and recommends some best practices for owners, designers, builders working on midcentury buildings which are suspected to contain these dangerous chemicals.

Umass Brut: Re-Imagining The Plinth, John Amodeo 2021 IBI Group

Umass Brut: Re-Imagining The Plinth, John Amodeo

UMassBRUT Community

Modeled on UVA’s Lawn, Paul Rudolph’s mid-century Brutalist UMass Dartmouth buildings march down both sides of a gently sloped great lawn following the grade with one exception, the Auditorium, which is raised above the quad’s lawn on a 6’ high plinth, accessed by monumental stairs underscoring the entire building. With its entries elusively tucked into the ends of the building, the Auditorium steps were ceremonial at best and vacant, functionless and windswept at worst.

Evolving tastes, priorities and social behavior over subsequent decades, and even more recently, the pandemic, have made indoor/outdoor relationships, outdoor space, and universal access a top …

Potentials Of Containers In Creating Modular Architectural Spaces, Karim Al-Khatib, Jinan Makkawi, Ali Kobeissi

Architecture and Planning Journal (APJ)

Containers are currently considered as one of the inventive trends of framing architectural objects. Container architecture is defined as the type of architecture that is characterised by the usage of steel containers as a structural elements and architectural envelope that can be presented as a part of architecture or a function that an activity can happen in it. Due to the specific dimensions that the container has, architects tend to use it to obtain modularity in their projects and the modular design strategies refer to using the containers as a standard unit to carry out the process, these containers are …

Simulation For A Mems-Based Ctrnn Ultra-Low Power Implementation Of Human Activity Recognition, Muhammad Emad-Ud-Din, Mohammad H. Hasan, Roozbeh Jafari, Siavash Pourkamali, Fadi M. Alsaleem

Faculty Publications in Architectural Engineering

This paper presents an energy-efficient classification framework that performs human activity recognition (HAR). Typically, HAR classification tasks require a computational platform that includes a processor and memory along with sensors and their interfaces, all of which consume significant power. The presented framework employs microelectromechanical systems (MEMS) based Continuous Time Recurrent Neural Network (CTRNN) to performHAR tasks very efficiently. In a real physical implementation, we show that the MEMS-CTRNN nodes can perform computing while consuming power on a nano-watts scale compared to the micro-watts state-of-the-art hardware. We also confirm that this huge power reduction doesn’t come at the expense of reduced …


Framework To Develop Time- And Voltage-Dependent Building Load Profiles Using Polynomial Load Models, ANDREW PARKER, Mhd Anas Alkrch, KEVIN JAMES, Ahmad Almaghrebi, Mahmoud Alahmad 2021 National Renewable Energy Laboratory

Framework To Develop Time- And Voltage-Dependent Building Load Profiles Using Polynomial Load Models, Andrew Parker, Mhd Anas Alkrch, Kevin James, Ahmad Almaghrebi, Mahmoud Alahmad

Faculty Publications in Architectural Engineering

The power consumption of buildings over the course of each minute, hour, day and season plays a major role in how this load influences the Electric Power System voltage and frequency, and vice versa. This consumption is based on the building's load component types, efficiencies, and how they consume power and react to changes in real time. Due to this complexity, standard full-building load models are typically voltage-invariant. This paper proposes a novel framework to transform these voltage-invariant building load models into fully time- and voltage-dependent load profiles using available data on the voltage sensitivity of individual load components. While …

Evaluating Prediction Models Of Creep And Drying Shrinkage Of Self-Consolidating Concrete Containing Supplementary Cementitious Materials/Fillers, Micheal Asaad, George Morcous 2021 University of Nebraska - Lincoln

Evaluating Prediction Models Of Creep And Drying Shrinkage Of Self-Consolidating Concrete Containing Supplementary Cementitious Materials/Fillers, Micheal Asaad, George Morcous

Faculty Publications in Architectural Engineering

Supplementary cementitious materials (SCMs) and fillers play an important role in enhancing the mechanical properties and durability of concrete. SCMs and fillers are commonly used in self-consolidating concrete (SCC) mixtures to also enhance their rheological properties. However, these additives could have significant effects on the viscoelastic properties of concrete. Existing models for predicting creep and drying shrinkage of concrete do not consider the effect of SCM/filler on the predicted values. This study evaluates existing creep and drying shrinkage models, including AASHTO LRFD, ACI209, CEB-FIP MC90-99, B3, and GL2000, for SCC mixtures with different SCMs/fillers. Forty SCC mixtures were proportioned for …
