Semi-rigid composite connections with precast hollowcore slabs are a newly developed technique with few applications in current construction practice. The research on the structural behaviour of this new type of connection is limited, with no existing method available to predict its important characteristics such as moment and rotation capacities. In this paper, based on the parametric studies of the three-dimensional finite element model and full-scale tests, analytical methods to calculate the moment and rotation capacity of this type of composite joint are proposed. A comparison between the proposed calculation method and the full-scale test results was made, and good agreement was obtained. © 2009 Elsevier Ltd. All rights reserved. Source

Travel plans are packages of measures tailored to meet the needs of individual sites, which aim to promote greener, cleaner travel choices and reduce reliance on the car. Travel plans deliver transport improvements in a cheap, quick, acceptable and effective way, but to work properly they require institutions such as employers and schools to participate, which they are often unwilling to do voluntarily. Consequently, in the UK travel plans are now often legally required by local authorities through the planning process. This means land developers are major travel plan stakeholders, yet little is known of their views. The aim of this paper is to help redress this by reporting the results of 10 exploratory interviews with informed developers on the topic. The paper highlights that developers are generally positive about travel plans, but have concerns relating to financial penalties and associated future costs. Recommendations are made for practice and policy. Source

The Shard in central London is 310 m high, making it the tallest building in western Europe. Designed for client Sellar Property Group, it is a 'vertical city', containing shops, offices, restaurants, hotel, apartments and a public viewing gallery. This paper describes the design and construction of the building, which has a concrete core, steelframed floors to level 40, concrete floors to level 69 and a steel 'spire' at the top. Various innovative construction techniques were used to save time and improve safety, including building the three-storey basement and core topdown, installing plunge columns to high levels of accuracy, and using modular construction for the spire.

It is only in Eurocodes that the concept of designing for specifically defined accidental actions using reduced partial safety factors has appeared in codes of practice outside the UK. This paper considers a range of accidental scenarios including gas explosion, bomb blast, burst water main, flood, roof ponding, car park barriers, horizontal human loads on barriers, snow load, ice accretion, wind load, helicopter hard landing, fire, and local failure. It is concluded that generally the Eurocodes identify accidental design situations successfully, but that both vehicle and human loading on barriers should be more explicitly and better treated, and that roof ponding and ice accretion should also be considered.

Method: Two groups of dogs were selected representing the normal Labrador Retriever population (n = 13) and Labrador Retrievers with confirmed MCD (n = 13). Normal dogs had “normal” hip and elbow radiographic scores in line with the International Elbow Working Group and British Veterinary Association guidelines. Medial coronoid disease was confirmed using arthroscopy after kinematic analysis was performed with a six degrees of freedom marker set.Results: The diseased elbow was nine degrees more extended between 43%-55% of the gait cycle and 16° more supinated prior, early during and after foot strike. The antebrachium was nine degrees more supinated during foot strike and three degrees more abducted during early stance. None of the other parameters were significantly different.Objectives: To determine if the use of a six degrees of freedom marker set would allow new kinematic data of the canine thoracic limbs to be calculated. To identify any significant differences in thoracic limb gait patterns in all planes of motion, between the normal canine population and patients with confirmed medial coronoid disease (MCD).Clinical significance: The use of a six degrees of freedom marker set made it possible for the elbow and antebrachium to be reliably tracked in more than one plane of motion. Significant differences were identified between the normal canine population and those affected by MCD. These data may help elucidate biomechanical factors contributing to aetiopathogenesis of MCD. © Schattauer 2014. Source
