Thermal Bridges in Insulation Systems

Advanced Materials Research, 2013
The article points out and describes in detail the basic thermal bridges in contact thermal insulation systems and in ventilated facades. Thermal bridges are illustrated by means of thermal images of spot thermal bridges and the calculation of spot heat transfer coefficients.

Thermal Calculations for Bridge Design

Journal of the Structural Division, 1975
A straightforward method is shown for calculating thermal stresses in bridges. Unsteady temperature distributions are obtained from numerical solutions of the one-dimensional unsteady heat equation, and comparison with experiment seems to validate the simplifying assumption that horizontal heat movements are small enough to be ignored.

Thermal loading of concrete bridges

Canadian Journal of Civil Engineering, 1984
This paper presents the results of a parametric study into the thermal loading of concrete bridges by solar radiation. All results were obtained using a computer model calibrated from field measurements. The model computes the loading parameters from the bridge characteristics and the standard daily records of the weather bureau.

Thermal behaviour of composite box-girder bridges

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2000
This paper investigates the behaviour of composite box-girder bridges subject to environmental thermal effects such as solar radiation, air temperature and wind speed. It is based on the statistical analysis of measured temperature data which were recorded hourly in a newly constructed composite box-girder bridge for about 20 months continuously ...

Elimination of Thermal Bridge by Thermal Insulation Composite Material

Advanced Materials Research, 2012
With the sustainable construction the emphasis is placed on energy savings, reducing of consumption of natural resources, extending of the life cycle of recycling, etc. The research has brought about a new material - thermal insulation composite material - which is formed by a combination of recycled polymers and inorganic fillers satisfying the ...

Thermal Bridging and Linear Thermal Transmittance Calculations for Balconies

2020
The thermal performance of building envelopes can be significantly affected by thermal bridging. Thermal bridges are localized areas of high heat flow through walls, roofs, and other insulated building envelope components. Thermal bridging is caused by highly conductive elements that penetrate the thermal insulation or misaligned planes of thermal ...

Designing the Thermal Bridges

2017
In a Passive House, it is necessary to design the thermal bridges; this does not necessarily mean eliminating them, but adopting the most suitable technical solution to make their dispersions compatible with the energy balance of the building.

Energy losses through thermal bridges

Batiment International, Building Research and Practice, 1979
In addition to unsightly condensation and even cracks, thermal bridges in a building envelope can cause considerable heat losses. Work at the Norwegian Building Research Institute, presented here, has tried to simplify the calculations involved so that the designer can quickly see if his design is ‘good’ or ‘bad’ in this respect.

Thermal Movement of Bridge Decks

Journal of the Structural Division, 1972
The object herein is to present the graphic solution approach for computing the in-plane (horizontal) thermal movements of curved bridge decks supported by a statically determinate system of lateral supports.

Surface Temperature a Thermal Bridges

Journal of Thermal Envelope and Building Science, 2001
The recent work aimed at the determination of the correct film coefficient value at design, since the practical experiences do not ensure the theory. It was proved by monitoring the film coefficient value along the edges and at thermal bridges and showing that it differs from the overall standard design value and varies in function with the ...
