Nonlinear Behaviour of Multi-Joist Timber-Concrete Composite Floors

本博士研究将使用试验和数值分析来了解木-混凝土复合材料（TCC）地板的准静力响应。其中一个重点将是使用带有多个木托梁的楼板样本，以便在先前的工作基础上进行研究，其中只研究了包含一个托梁的板宽度的单个截面。为此，将制作和测试少量的多梁TCC试件，并使用重要的仪器来研究诸如单个截面TCC之间的负载分担等问题。非线性有限元将用于尝试和预测所测负载响应。使用经过验证的有限元作为工具进行广泛的参数研究将是该工作的一个关键特征，该工作由IStructE资助，并与ARUP合作。发表期刊论文（Joshua和我以及来自意大利trentuniversity的合著者已经在之前的TCC工作中完成了这一工作）将是这项工作的重点，同时也将利用任何可能的机会向行业进行介绍。

This PhD study will use both tests and numerical analyses to understand the quasi-staticload responses of timber-concrete composite (TCC) floors. One emphasis will be the use offloor specimens with multiple timber joists, so as to build on previous work where a single Tsectioncomprising a width of slab with just one joist has been investigated. To that end, asmall number of multi-joist TCC specimens will be fabricated and tested, with significantinstrumentation used to work backwards to issues such as load-sharing between individualT-section TCCs. Nonlinear FE will be used to try and predict the measured load responses.Use of the verified FE as a tool to conduct wide-ranging parametric studies will be a keyfeature of the work, which is IStructE - funded and includes collaboration with ARUP.Publishing of journal papers (which Joshua and I along with co-authors from TrentoUniversity in Italy have already done on previous TCC work) will be a focus of this work, aswill presentations to industry at any available opportunity.
