The Influence of Tensile Membrane Action on Fire-exposed Composite Concrete Floor-steel Beams with Web-openings
Abstract On the basis of a series of the full-scale fire tests carried out on the composite frame at Cardington, a design method is now well established to calculate the performance of composite flooring systems subject to fire. The method models in ...

Reliability of Asymmetrically Reinforced Columns
Abstract The criterion of reliability - compulsory minimal eccentricity was verified by axially loaded columns which were unsymmetrical reinforced. By design of concrete columns a condition of min eccentricity (emin= h/30 resp. 20mm) has to be...

The Evaluation of a Palette of Low Carbon Measures Applied to a Conservation Area Victorian Terraced House
Abstract There exists a solution gap between the design of new build UK housing and the low carbon retrofit of existing housing stock. Whilst a series of common standards can be reasonably applied to new construction, many factors (such as age,...

Non-uniform Sediment Transport Estimation in Non-equilibrium Situations: Case Studies
Abstract Quantitative estimate of sediment transport in alluvial channels is one of the most important task in river engineering. Even today, numerical models of sediment transport processes are confronted with some difficulties, often of conceptual ...

Innovative solutions please, as long as they have been proved elsewhere: The case of a polished lime-pozzolan concrete floor
Abstract This case-study paper tells the story of the development of a bespoke lime-pozzolan concrete for an innovative project application. In this paper, the results of laboratory testing are contextualised by the project-story that steered the...

Optimal Design of District Metered Areas in Water Distribution Networks
Abstract The paper presents a multi-objective approach for the automatic partitioning of a water distribution network into District Metering Areas (DMAs). In the proposed methodology, both technical and economic issues are considered, including...

Strength of Jack-Beams with slender webs and mono-symmetric sections
Abstract Jack-Beams (J-Beams) are used to support discontinued columns that do not extend to lower floors, satisfying space requirements in large stores and workshops. Often large concentrated loads are acting on the laterally unsupported J-Beam...

STATBOX Concept for Simulation of Urban Phenomena
Abstract An urban environment is a dynamic system which is constantly changing in terms of space and time. There are two dimensions in any urban environment – the physical dimension and the functional dimension. All of the structures of an urban...

Optical Multi-Sensor-Measurements in the Shop by Compensating Environmental Influences
Abstract Optical Multi-Sensor-Measurements in the shop are often affected by external influences which dominate the quality of the measurements and disable low uncertainties. In this approach simulations are carried out to estimate the uncertainty...

Impacts of Driving Behaviours, Slope and Vehicle Load Factor on Bus Fuel Consumption and Emissions: A Real Case Study in the City of Rome
Abstract Bus fuel consumption and air pollutant emissions are related to technological aspects, such as engine efficiency, type of gear as well as physical parameters, such as slope of the infrastructure, vehicle weight, vehicle load and so on; on...

QMRA in the Drinking Water Distribution System
Abstract A Quantitative Microbial Risk Assessment (QMRA) model was developed for contamination events after mains repairs. The sensitivity analysis showed that the contamination concentration is the most important parameter, next to the pathogen...

Performance Indicators for Planning Intermodal Barge Transportation Systems
Abstract Various indicators are used to qualify the performance of intermodal transportation systems. Some of these are found in public documents, usually providing global measures such as total flow volumes, profits, and share values. While of...

Bearing capacity of circular footing resting on granular soil overlying soft clay
Abstract The bearing capacity of footings constructed on soft clay soil is considerably governed by soil settlement. In practice, the bearing capacity of foundations on soft clay can be improved by a layer of compacted sand or gravel. In this study...

Post-buckling analyses of variable-stiffness composite cylinders in axial compression
Abstract Variable-stiffness shells are thin composite structures in which the reinforcement direction is a function of its surface co-ordinates. This paper presents a numerical investigation into the buckling and post-buckling of two...
