Book Description
This volume gathers the latest advances, innovations, and applications in the field of seismic engineering, as presented by leading researchers and engineers at the 1st International Workshop on Energy-Based Seismic Engineering (IWEBSE), held in Madrid, Spain, on May 24-26, 2021. The contributions cover a diverse range of topics, including energy-based EDPs, damage potential of ground motion, structural modeling in energy-based damage assessment of structures, energy dissipation demand on structural components, innovative structures with energy dissipation systems or seismic isolation, as well as seismic design and analysis. Selected by means of a rigorous peer-review process, they will spur novel research directions and foster future multidisciplinary collaborations.

Book Description
As mass timber becomes increasingly popular in the United States and around the world, there comes more demand for mass timber in larger buildings. With this demand comes a necessity for these buildings to be able to withstand seismic forces; and in some locations, these forces can get quite high. Typical mass timber lateral systems (such as CLT shear walls) have worked fine for lower seismic forces and shorter buildings, but with this new demand comes a need for newer systems. Rocking timber walls is one of these systems. The goal of a rocking timber wall is to allow the lateral wall system to move in the case of high seismic force, thus reducing the loading the wall experiences. This is done with vertical post tensioning (PT) within cross-laminated timber panels (CLT). In addition, easily replaceable energy dissipation devices, such as U-shaped flexural plates (UFPs), allow for concentration of inelastic deformation during rocking of the walls, which keeps the CLT and PT components free from harm. Another system used to handle seismic load in tall mass timber structures are inter-story isolation systems. These systems can isolate the force at separate levels, effectively decreasing the load the foundation takes from the building's movement. Even newer than these systems is the Floor Isolated Re-centering Modular Construction System (FIRMOC), which utilizes rocking timber walls, inter-story isolation, and the addition of prefabricated modular mass timber to create a system capable of effectively and efficiently dealing with large seismic forces. This report seeks to present these innovative, capable, and effective lateral systems for seismic forces in large scale mass timber structures in a manner that provides understanding of how they work and what makes them effective.

Book Description
This report summarizes the proceedings, including key points and identified research needs, that evolved from the Mass Timber Research Workshop, which was held at the USDA Forest Products Laboratory (FPL), November 3-4, 2015. The purpose of the workshop was to bring design professionals, researchers, and industry leaders together to examine the state-of-the-art in mass timber construction, with an emphasis on cross-laminated timber, and to identify technical barriers to the broader use of wood in engineered structures that need to be addressed. Following a plenary session on mass timber in North America, some 120 scientists, engineers, and industry leaders heard presentations organized in four technical areas: (1) resistance to lateral loads, (2) building performance-durability, sound, vibration, and life cycle assessment, (3) fire safety, and (4) material resources and other research topics. Breakout sessions aimed at identifying future research objectives were then held for each of the four technical areas, followed by a prioritization of future research needs. Included in these proceedings are abstracts from each presentation, copies of all presentations and a summary of research needs.

Book Description
Timber construction is one of the most prevalent methods of constructing buildings in North America and an increasingly significant method of construction in Europe and the rest of the world. Timber Engineering deals not only with the structural aspects of timber construction, structural components, joints and systems based on solid timber and engineered wood products, but also material behaviour and properties on a wood element level. Produced by internationally renowned experts in the field, this book represents the state of the art in research on the understanding of the material behaviour of solid wood and engineered wood products. There is no comparable compendium currently available on the topic - the subjects represented include the most recent phenomena of timber engineering and the newest development of practice-related research. Grouped into three different sections, 'Basic properties of wood-based structural elements', 'Design aspects on timber structures' and 'Joints and structural assemblies', this book focuses on key issues in the understanding of: timber as a modern engineered construction material with controlled and documented properties the background for design of structural systems based on timber and engineered wood products the background for structural design of joints in structural timber systems Furthermore, this invaluable book contains advanced teaching material for all technical schools and universities involved in timber engineering. It also provides an essential resource for timber engineering students and researchers, as well as practicing structural and civil engineers.

Book Description
As mass timber continues to increase in popularity as a primary structural material, it is desirable to develop efficient, ductile lateral force resisting systems (LFRS). A timber buckling restrained brace (TBRB) is presented as a possible solution for creating seismically resilient timber buildings. Like conventional buckling restrained braces (BRB), the TBRB utilizes a steel yielding core, but the restraining element is mass ply panel (MPP) blocks instead of the conventional concrete-filled steel tube. To understand the failure modes and moment-rotation relationship of the beamcolumn connections, six mass ply lam (MPL) beam-column connections were tested with various dowel layouts under monotonic and cyclic loading protocols. The joints achieved rotations of 0.11 radians (6.3 degrees) without visible external connection damage. Next, two sets of testing series were adopted for testing the TBRB frames (TBRBF). In the first testing series, four TBRBF tests were completed with varying levels of axial force in the columns. Bare frame tests were also completed to observe the stiffness degradation throughout the testing series. The TBRBFs achieved a story drift ratio exceeding 2.8% before TBRB failure. The primary failure mode was splitting of the casing caused by weak-axis bucking of the core near the ends of the yielding zone. In the second TBRBF testing series, three TBRBs were tested. Two of the three TBRBs were enhanced with carbon fiber wrap at the ends of the casing to avoid the premature failure of the casing observed during the first testing series. The carbon fiber wrap allowed the TBRBF to achieve 4.5% drift ratio and changed the failure mode of the TBRB to tensile fracture of the steel core. Finally, the bare timber frame was tested up to 8.0% drift ratio. Finally, numerical models for the TBRB and beam-column connections were developed and combined into a single-story frame model. The model was validated by the TBRBF experimental results. After validation, the model was extrapolated into an eight-story TBRBF. The model was studied under pushover, cyclic, and earthquake loads. Moreover, the results of the model combined with the experimental results present the TBRBF as a feasible LFRS for resilient timber buildings.

Book Description
The Design-Build Studio examines sixteen international community driven design-build case studies through process and product, with preceding chapters on community involvement, digital and handcraft methodologies and a graphic Time Map. Together these projects serve as a field guide to the current trends in academic design-build studios, a window into the different processes and methodologies being taught and realized today. Design-build supports the idea that building, making and designing are intrinsic to each other: knowledge of one strengthens and informs the expression of the other. Hands-on learning through the act of building what you design translates theories and ideas into real world experience. The work chronicled in this book reveals how this type of applied knowledge grounds us in the physicality of the world in which we live.
