Abstract
Purpose
This paper aims to propose a methodology to remove inherent implicit creep from the Eurocode 3 material model for steel and to present a creep-free analysis on simply supported steel members.
Design/methodology/approach
Most of the available material models of steel are based on transient coupon tests, which inherently include creep strain associated with particular heating rates and load ratios.
Findings
The creep-free analysis aims to reveal the influence of implicit creep by investigating the behaviour of simply supported steel beams and columns exposed to various heating regimes. The paper further evaluates the implicit consideration of creep in the Eurocode 3 steel material model.
Originality/value
A modified Eurocode 3 carbon steel material model for creep-free analysis is proposed for general structural fire engineering analysis.

Abstract
The development of new, inexpensive, robust and miniaturised sensors is continuously being sought and it is believed that thick‐film technology can help to achieve these goals. A strain sensor utilising the piezoresistive properties of thick‐film resistors is described here. Characterisation of the sensing element has revealed that the gauge factor is significantly higher than that of metal foil strain gauges and the temperature coefficients are generally lower than those found for semiconductor strain gauges. Results show how the gauge factor can be optimised by varying the production parameters.

Abstract
Standards play an increasingly important role in the development of the “global village”, both from the economic and the quality of life perspective. However, development of standards should always be in tune with the needs of a free economy, whose main engine is differentiation. Standardization and differentiation can be complementary, but only to the extent that a correct balance between the two is kept. The balance becomes particularly delicate when standards move from product‐related issues to organization‐related issues, as is the case of quality system standards. Starting from a brief review of ISO 9000 and its role in the past decade, then moving to Vision 2000, the paper expresses reservations about the benefits and opportunity for standards to enter the organizational improvement area. In a situation of continuous change and global competition, differentiation seems to be the name of the game, more than standardization. Instead, a kind of “standards syndrome” seems to take place, where standards are expected to legitimize managers’ choices.
