Abstract Purpose This paper aims to describe current trends in probabilistic structural fire engineering and provides a comprehensive summary of the state-of-the-art of performance-based structural fire engineering PSFE.
Findings This paper brings together existing research on various sources of uncertainty in probabilistic structural fire engineering, such as elements affecting post-flashover fire development, material properties, fire models, fire severity, analysis methods and structural reliability.

The aim of this Task Group is to focus on minimising energy consumption and non-renewable resources during the life-time of structures from the structural point of view.
Basically, the structures built using current specifications are durable.

Therefore, structural sustainability should be defined as the difference from existing technologies to new ones in order to make structural sustainability clear. Examples of structural type, detailing, design, special construction techniques and so on for structural sustainability will be collected to publish a state-of-the-art report. During the long history of CEB, FIP and now fib , the main objectives of their commissions, task groups and special activity groups were and are actual topics of research, application and dissemination.
Construction history is a rapidly growing research field in the community of architects and civil engineers. The last conference on construction history took place in Paris in July and consisted of 66 sessions. Only two of them focused on concrete and concrete construction. Furthermore, none of the key lectures was related to concrete. The task group intends to set up a process which shall result in the publication of a series of bulletins covering the global history of structural concrete, from its first developments to the present situation.

At the beginning, it is very important to organise the extremely broad field of historic research. It is suggested to start with a narrower approach, mainly with the collection of historic material. A broader approach implies the integration of concrete history within the time, including political, social, climatic, economic and ecological circumstances. This will require more time as well as the addition of historically educated experts.
The areas of interest have been developed from the viewpoint that the construction process has two main components: perception related aspects and process aspects. The process related aspects comprise the construction process of concrete structures, quality management and life cycle management. The task group addresses state-of-the-art basic principles of the construction process of concrete structures at site. Furthermore, the task group reflects on anticipated developments, which could have a significant influence on construction.
The objective is to develop awareness regarding aspects which have an impact on safety, serviceability, durability and environmental issues of concrete structures to be built on site, and to provide information as how to handle the basic principles. The output will be presented as internationally harmonised reports.
India Gammon India Ltd. Concrete is often used for industrial floors that are designed to withstand static and dynamic loads as well as the degradation caused by operations and the environment. Industrial floor must be properly designed for resisting point and distributed loads due to shelves and vehicles present on the floor. Seismic action transmitted by shelves must be considered in seismic areas. Shrinkage phenomena play a major role since they provoke early age cracks that can be controlled by contraction joints that are likely to damage due to wheel crossing.
Another important issue is represented by the top finishing layer that had to be properly designed to resist abrasion. Main scope of the Task Group is to briefly describe the most important issues in concrete technology for industrial floors, give relevant references to important literature, describe important design premises, give guidance to potential improvements and maintenance. Some attention will be also devoted to refurbishing of existing floors. Join the fib. Membership Commissions and Task groups.

Convener Steffen Marx. The scope of WP 1. The objective of these guidelines is to define the current best practical response to specific problems associated with semi-integral and integral bridges from an international perspective. It will be based on existing guidelines, results from scientific research and feedback from practical experience. Convener TBD. While road and railway bridges benefit from standards and extensive documentation often published by state agencies, it is not the case for lightweight railway bridges.
However, from a bridge engineering perspective, common features, particular requirements and good practices for design and construction that specifically apply to these transportation modes can be identified. The general objective of this working party is to provide a state-of-the-art report for the design of LRT and MRT bridges.
Over recent years some significant work has gone into inspection and investigation of post-tensioned bridges around the world. This has led to an increase in understanding the methods of inspection to determine the condition of the prestressing tendons and the whole process to assess structural safety.
