Purpose This paper aims to explore and discuss the concept of brand forgiveness. It empirically assesses the relationships among three types of brand transgressions, brand forgiveness and three consumer coping strategies. Design/methodology/approach A 3 × 2 research design is used to evaluate the effects of three types of brand transgression (performance, image and value) and two degrees of severity (high vs low) for brand forgiveness. Then, this paper use a 2 × 3 research design, evaluating two degrees of brand forgiveness (high vs low) together with their effects on three different consumer coping strategies (switching, attacking and purchasing again). Using a representative sample of 472 US consumers, various hypotheses related to these research designs are tested. Findings The results show that almost half (48 per cent) of the consumers are unlikely or very unlikely to forgive a brand compared to about a third (32 per cent) who are likely or very likely to forgive. The results of ANOVA show the more severe the brand transgression, the less likely the forgiveness. Consumers who are more likely to forgive are less likely to avoid the brand or engage in attacking behaviors; they are also more likely to purchase the brand again. The results of regression analyses show that consumers witnessing a performance-based brand transgression are more likely to forgive the brand than in the case of image- or value-based brand transgressions. Originality/value This paper explores and outlines the brand forgiveness construct, both theoretically and empirically.

Abstract. The purpose of this research is to collect fundamental data and to establish a performance-based design method for reinforced concrete beams under perpendicular impact load. Series of low speed impact experiments using reinforced concrete beams were performed varying span length, cross section and main reinforcement. The experimental results are evaluated focusing on the impact load characteristics and the impact behaviours of reinforced concrete beams. Various characteristic values and their relationships are investigated such as the collision energy, the impact force duration, the energy absorbed by the beams and the beam response values. Also the bending performance of the reinforced concrete beams against perpendicular impact is evaluated. An equation is proposed to estimate the maximum displacement of the beam based on the collision energy and the static ultimate bending strength. The validity of the proposed equation is confirmed by comparison with experimental results obtained by other researchers as well as numerical results obtained by FEM simulations. The proposed equation allows for a performance based design of the structure accounting for the actual deformation due to the expected impact action.

This paper outlines a performance-based seismic design methodology for steel bridge systems. Two kinds of menus are proposed. The first is the displacement-based evaluation method which compares the response displacement with the ultimate displacement, and the second is the strain-based evaluation method which compares the response strain and the ultimate strain. Moreover, the seismic required performance matrix for bridge structures and soundness matrix for members are presented and discussed.
