“…14a). During the course of the Pres-Lam project several authors have used this approach to predict the static performance of experimental testing (Cusiel et al 2010;Newcombe et al 2010;Smith et al 2014), however the ability of the technique to predict dynamic response required further study.…”

A recently developed technology for the construction of multi-storey timber buildings called Pres-Lam uses long lengths of prefabricated laminated timber connected together using pre-stressing steel tendons or bars. A 3-dimensional, 3-storey, 2/3rd scaled Pres-Lam frame building was tested on the shaking table of the structural laboratory of the University of Basilicata. The main objectives of this study were: (1) to confirm the effectiveness of the Pres-Lam technology, originally developed using laminated veneer lumber, for glue laminated (Glulam) timber structures and (2) to validate the current modelling approach in predicting the dynamic response. This paper describes the design, detailing and construction of the experimental model followed by explanation of the testing programme. Two sessions of testing were performed considering different column-base conditions, both with and without the activation of externally mounted dissipative steel angles. The test results are compared with numerical predictions obtained through nonlinear analysis. These numerical models are shown to provide an accurate representation of the dynamic response.

“…Due to its high homogeneity and good mechanical properties, laminated veneer lumber (LVL) was initially selected as the preferred engineered wood material for the first phase of the research and development. However, any other engineered wood product as Glulam or Cross-lam (X-lam) can be adopted as shown by recent experimental tests and numerical analyses on both materials (Smith et al 2014;Dunbar et al 2014).…”

The 2010-2011 Canterbury earthquake sequence has highlighted the severe mismatch between societal expectations over the reality of seismic performance of modern buildings. A paradigm shift in performance-based design criteria and objectives towards damage-control or low-damage design philosophy and technologies is urgently required. The increased awareness by the general public, tenants, building owners, territorial authorities as well as (re)insurers, of the severe socio-economic impacts of moderate-strong earthquakes in terms of damage/dollars/downtime, has indeed stimulated and facilitated the wider acceptance and implementation of cost-efficient damage-control (or low-damage) technologies.The 'bar' has been raised significantly with the request to fast-track the development of what the wider general public would hope, and somehow expect, to live in, i.e. an "earthquake-proof" building system, capable of sustaining the shaking of a severe earthquake basically unscathed.The paper provides an overview of recent advances through extensive research, carried out at the University of Canterbury in the past decade towards the development of a low-damage building system as a whole, within an integrated performance-based framework, including the skeleton of the superstructure, the non-structural components and the interaction with the soil/foundation system.Examples of real on site-applications of such technology in New Zealand, using concrete, timber (engineered wood), steel or a combination of these materials, and featuring some of the latest innovative technical solutions developed in the laboratory are presented as examples of successful transfer of performance-based seismic design approach and advanced technology from theory to practice.

“…The experimental campaign, carried out considering a 3D, 2/3 scaled timber frame, is part of a collaboration between the University of Basilicata (UNIBAS, Italy) and the University of Canterbury (UoC, New Zealand) (Di Cesare et al, 2012. The project aim is to evaluate the feasibility of applying jointed ductile post-tensioning technology to glue-laminated (glulam) timber (Smith et al, 2014), a more widespread engineered timber material, and to evaluate the increasing seismic performance due to the addition of various dissipative forms based on rocking mechanisms and on bracing systems.…”

This paper describes a seismic design procedure for low-damage buildings composed by post-tensioned timber framed structures coupled with hysteretic dissipative bracing systems. The main goal of the design procedure is preventing or limiting earthquake-induced damage to the structural and non-structural elements. For this aim, a target design displacement is defined according to the desired performance level. Then, the corresponding design force, strength, and stiffness of the post-tensioning and of the dissipative braces are evaluated in order to size post-tensioned connections and dissipating devices. The results of shaking table testing performed at the University of Basilicata are also reported. A prototype model −2/3 scaled, three-dimensional, and three stories with a post-tensioned timber structure without and with V-inverted braces and U-shaped flexural steel dampers-has been extensively tested. During testing, the specimen was subjected to a set of seven earthquakes at different intensity levels of the peak ground acceleration. The effectiveness of the bracing system and the reliability of the proposed procedure are experimentally demonstrated. Non-linear dynamic analyses have been performed in order to simulate the experimental seismic response. The numerical model is based on a lumped plasticity approach, which combines the use of elastic elements with linear and rotational springs representing energy dissipating devices and plastic rotations of the connections. The numerical results accurately predict the non-linear behavior of the prototype model, obtaining a satisfactory matching with the target drift considered for design.
