A Three‐Parameter Continuum Timoshenko Beam Framework for Evaluating Higher‐Mode Effects in High‐Rise Buildings With Rotational and Translational Base Flexibility

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Higher‐mode effects can significantly amplify seismic demands in high‐rise buildings, causing unintended damage over the building height. Engineered mechanisms are introduced at the base of these structures to mitigate higher‐mode effects. Existing continuum formulations for base‐flexible buildings commonly idealize the superstructure as a ...

Global state of knowledge on human-induced sound and vibration events: defining future research directions for mass timber products

Journal of Wood Science
Despite the rise in mass timber buildings globally, challenges remain with timber’s limitations in low-frequency sound and vibration. This is due to timber’s lower density compared to concrete and steel, leading to natural frequencies more susceptible to

Fire Safety of Mass timber Buildings with CLT in USA

Wood and Fiber Science, 2018
Multistory buildings using mass timber and cross-laminated timber (CLT) as the primary structural elements are being planned and constructed globally, with interest starting to gather momentum in the United States. Model building codes in the United States limit timber construction to a building height of 85 ft (25.9 m) because of concerns over fire ...

Whole‐House Thermal Bridge Modelling for Accurate Retrofit Energy Prediction

Energy Science &Engineering, EarlyView.
This study models thermal bridging in a UK semi‐detached house across pre‐ and post‐retrofit scenarios using piecemeal and whole‐house approaches with EWI and IWI. Whole‐house retrofits reduce heat transfer coefficient by 60%; findings demonstrate that default values are often unrepresentative and advocate tailored Ψ value databases.

Mass Timber and the Disruption of the Building Sector

Over the past decade, the resurgence of engineered wood products, such as cross-laminated timber for buildings, has inspired a change in the way we build. Driven by an effort of the construction sector to become more sustainable and have lower carbon impacts, cross-laminated timber presented an opportunity to try to build better.

Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile

Fire and Materials, EarlyView.
ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.

Seismic performance evaluation of mass timber buildings equipped with resilient and conventional friction devices

Resilient Cities and Structures
The application of mass timber elements in different structures has gained publicity over the last few years, primarily due to climate change adaptation policies and net zero carbon targets. Timber is a renewable construction material that can outperform
