Structural performance of cross laminated timber (CLT) buildings under dynamic load

Overview:
Cross Laminated Timber (CLT) has become a widely used engineered timber product, and the primary structural material for Mass Timber Construction, an approach that is expected to contribute substantially to reducing the CO2 emissions of the construction industry. With a growing number of CLT buildings appearing across Europe, interest in the system is increasing, particularly for mid-rise residential sector projects where traditional timber systems are not a cost-effective option. CLT is a renewable, green and sustainable material, which creates low carbon or carbon neutral developments. CLT is a relatively light building material which is a desirable quality for mid- and high-rise CLT building in particular in earthquake-prone regions in Europe or the US. While CLT is now frequently used for the mid-rise residential sector, the next step is to consider how CLT can apply to taller structures. However, high rise CLT construction remains unproven in seismic zones, while its novelty means that it has a limited track record under complex dynamic loads. This project aims to investigate the performance of mid- and high-rise CLT buildings under wind loads and seismic excitation. To do so, strong data from a full-scale shaking table test will be used to develop and validate structural computer models for CLT buildings. The project involves data processing/analysis of experimental investigations and developing/validating finite element (FE) models for CLT buildings.

Person specification
A valid English language qualification, such as International English Language Test System (Academic IELTS) or equivalent with an overall score of 6.5 with no band below 6.0, must be submitted with your application.
We are looking for an enthusiastic and highly motivated candidate who should have or be in the process of obtaining an excellent first degree (a 2:1 or above) or MSc degree with Distinction, preferably in a relevant engineering discipline (e.g.Civil, Environmental or Chemical Engineering), or in Mathematics/Physics, or in Physical Geography, or in a related discipline. The role will involve field visits to obtain primary datasets through tracer tests, analyses of data, and development of a model.
Thus applicants should demonstrate
Good knowledge of dynamics, structural analysis, material behaviour, computer modelling and data processing using Matlab
Experience in structural modelling using OpenSees and ANSYS.
Good written and oral communication skills are essential.
Knowledge and experience of laboratory testing would be an advantage.

Funding notes
The opportunity is open to Home, EU and International applicants who meet the required Birmingham City University eligibility criteria. The PhD studentship includes a full stipend, paid for a period of 3 years at RCUK rates (in 2019/20 this is £15,009 pa) and fees at Home/EU rate. This studentship is available for September 2019 start and no later than January 2020. International applicants are eligible to apply for this studentship but must meet the shortfall on fees between Home/EU and International rate.
