TL;DR: In this paper, the authors proposed a theoretical method for predicting residual stresses due to cold-rolling, which lead to a better knowledge of the characteristics of the cold rolling (elastic spring-back, effect of the ratio of the thickness versus the radius of the corner, distribution and size of the residual stresses with respect to the dimensions of the profiles).

TL;DR: In this paper, the authors discuss various composites and their manufacture, give values of mechanical properties for these different manufacturing techniques and states which technique is most relevant for specific structural applications.

TL;DR: In this article, the effects of surface treatment of polypropylene fibres on the compressive strength of reinforced concrete was investigated and a 3500 psi concrete design mix with Portland Type 1 cement was used as the base-composite and control group.

TL;DR: In this article, the properties of Parafil ropes with aramid core yarns are described, which offer the civil engineer a totally new structural material with exciting properties, as well as some actual and projected applications.

TL;DR: In this article, the most representative directions of research in the title subject are examined and discussed from the viewpoint of their input to both the knowledge of composite materials behaviour and to the building practice.

TL;DR: In this paper, the results of an extensive laboratory investigation where high-strength geogrids were employed, to strenghten granular road bases subjected to traffic load conditions were presented.

TL;DR: In this article, the influence of mixing and casting techniques and of curing time upon the compressive strength and hardness of methyl methacrylate-based polymer concrete was made of experimental studies, and the Rockwell K and F scales were found to be suitable for the hardness determinations.

TL;DR: The use of glulam in the UK is now increasing after many years of decline and the recent formation of a British Glued Laminated Timber Association is intended to co-ordinate technical and promotional effort aimed at further developing the UK market for Glulam as discussed by the authors.

TL;DR: In this article, the performance of glass fiber scrims with Teflon or silicone coatings has been explored and their performance record is discussed, and the viability of fabric for future construction is evaluated.

TL;DR: In this paper, a relatively simple experimental procedure for evaluating the thermal degradation of polymer concrete is described and the results of testing two distinct polymer concretes (one based on methyl methacrylate and the other on a polyester) are presented.

TL;DR: In this article, it is shown that the process of tunnelling involves a complex redistribution of stress around the excavation as it proceeds and that the interrelationship between the loads and deflections to which the lining is subjected during construction and the final state stresses following consideration of the structure/ground interaction.

TL;DR: In this article, the applicability of design code classification systems to various types of structure is reviewed with particular reference to the problems of thin sections, sections subjected to a hydrostatic pressure on one side only, sections subject to alternate wetting and drying, and sections partially immersed.

TL;DR: In this article, the pull-out test results of epoxy-coated and galvanized ribbed reinforcing strips are reported and compared and the results have been used to predict the developed tensile stresses within the reinforcing strips of recent reinforced earth retaining wall construction using a numerical finite element method of analysis.

TL;DR: The Steel Construction Institute (SCI) as discussed by the authors was established with the overall objective of promoting the most effective use of steel in construction through research and development, educational activities, the provision of advisory and information services and the dissemination of information through publications, seminars and conferences.

TL;DR: In this paper, the AMIR compactor was used to prevent the formation of constitution cracks resulting in an increase of indirect tensile strength of 10% and an increase in direct tensile strengths of up to 60% when compared to steel roller compacted asphalt slabs.

TL;DR: In this article, it is shown that many elements and sub-assemblies have a high degree of inherent fire resistance and indeed may not need the application of fire resistance materials to achieve the required fire rating.

TL;DR: In this paper, an in situ penetration hardening agent can prove more economical than conventional repairs of concrete screeds, despite considerable research, failure is still commonplace, and a recent example of a failure indicates how costly these can be.

TL;DR: In this paper, sound insulation is defined as the sound insulation provided by acoustic terminology such as insulation, absorption, isolation, and isolation, which is commonly misused by the layman; expressions such as "insulation", "absorption", and "isolation" appearing to be freely interchangeable.

TL;DR: In this article, the cause and extent of floor vibration is investigated and construction measures for improving the vibrational performance of timber floors are proposed. But, only recently, any research work has been undertaken in the UK to investigate this problem.

TL;DR: In this paper, the fundamentals for fire design of concrete beams and slabs are discussed, and several different models for temperature-time curves of fire exposure are discussed. But the exact design parameters are not discussed.

TL;DR: The use of fiber reinforced composites in the construction industry is well established as mentioned in this paper, however, if the proper technology is capable of handling all situations from a mechanical/architectural point of view, it is recognised that the fire hazard required a critical survey of the use of polymer materials.

TL;DR: In this article, the British Standard test was used to determine the vapour resistance and resistivity of building materials, and a more realistic quantity, such as the differential vapour permeability, was used for determining the flow rate through a porous material.

TL;DR: In this paper, the authors argue that reinforced composite component should become a more integral part of the building design and propose a better understanding of both the needs and requirements of the purchaser and of the wide ranging quality component which the supplier can increasingly offer.

TL;DR: In this article, the results of a factorial experimental design study into the possible use of industrial waste as feedstock for the manufacture of hydraulic cement were presented and research techniques used to select those most suitable are described.

TL;DR: In this paper, it is accepted that only when the fundamentals of reinforced concrete design and the implications of structural analysis are understood can satisfactory repairs be undertaken to structures suffering from any form of distress In order to effect successful repairs, the same degree of professional expertise as the original design required is necessary.
