Abstract

Purpose

This study investigates the impact of the fire decay phase on structural damage using the sectional analysis method. The primary objective of this work is to forecast the non-dimensional capacity parameters for the axial and flexural load-carrying capacity of reinforced concrete (RC) sections for heating and the subsequent post-heating phase (decay phase) of the fire.

Design/methodology/approach

The sectional analysis method is used to determine the moment and axial capacities. The findings of sectional analysis and heat transfer for the heating stage are initially validated, and the analysis subsequently proceeds to determine the load capacity during the fire’s heating and decay phases by appropriately incorporating non-dimensional sectional and material parameters. The numerical analysis includes four fire curves with different cooling rates and steel percentages.

Findings

The study’s findings indicate that the rate at which the cooling process occurs after undergoing heating substantially impacts the axial and flexural capacity. The maximum degradation in axial and flexural capacity occurred in the range of 15–20% for cooling rates of 3 °C/min and 5 °C/min as compared to the capacity obtained at 120 min of heating for all steel percentages. As the fire cooling rate reduced to 1 °C/min, the highest deterioration in axial and flexural capacity reached 48–50% and 42–46%, respectively, in the post-heating stage.

Research limitations/implications

The established non-dimensional parameters for axial and flexural capacity are limited to the analysed section in the study owing to the thermal profile, however, this can be modified depending on the section geometry and fire scenario.

Practical implications

The study primarily focusses on the degradation of axial and flexural capacity at various time intervals during the entire fire exposure, including heating and cooling. The findings obtained showed that following the completion of the fire’s heating phase, the structural capacity continued to decrease over the subsequent post-heating period. It is recommended that structural members' fire resistance designs encompass both the heating and cooling phases of a fire. Since the capacity degradation varies with fire duration, the conventional method is inadequate to design the load capacity for appropriate fire safety. Therefore, it is essential to adopt a performance-based approach while designing structural elements' capacity for the desired fire resistance rating. The proposed technique of using non-dimensional parameters will effectively support predicting the load capacity for required fire resistance.

Originality/value

The fire-resistant requirements for reinforced concrete structures are generally established based on standard fire exposure conditions, which account for the fire growth phase. However, it is important to note that concrete structures can experience internal damage over time during the decay phase of fires, which can be quantitatively determined using the proposed non-dimensional parameter approach.

Abstract

Purpose

The purpose of this paper is to explore the interface between Lean strategy and organisational transformation by scrutinising the literature on why Lean strategies fail to be implemented and/or sustained.

Design/methodology/approach

As a conceptual and research paper, it develops a hypothesis. It encompasses philosophical discussions and comparative studies of others’ work and Lean thinking alongside its links to the principles, ideology, philosophy and underpinning values. The search involved a total of 1,931 articles spanning across 75 different journals. The content analysis approach suggested by Mayring (2004) was selected.

Findings

Successfully implementing Lean is more complex than often recognized within the literature, and the alignment between strategy and organisational transformation is repeatedly not undertaken. The investigation indicates policymakers need to view Lean as an ideology and not simply another process.

Research limitations/implications

This paper addresses the inaccurate representation in the concept of Lean as a strategy. While a major evolution has occurred comprising the inputs perceived as imperative for Lean success, a translucent empathy of its philosophy alongside an acknowledgement of the magnitude of the change and transformation necessary has been comparatively perplexing. This paper has implications for academic scholars of strategy and organisational change, as well as for practitioners seeking to implement organisational change.

Originality/value

Empirical evidence suggests that most Lean strategies struggle. Customers are becoming more demanding, markets are becoming more customised, and product life-cycles getting shorter are dictating that Lean needs to be embraced as an ideology.

Abstract

Retailing has developed from independent merchants to multinational giants operating through global value chains, which has profoundly shaped consumption patterns in Western economies. This constant development currently consists of three global-scale change trajectories – climate change, online consumption, and technological development – that affect the retail industry. Based on this, this chapter concentrates on connecting the development paths of consumption and retailing and identifies various factors that affect the future of international retailing. The authors analyze the changes in institutional logics of international retailing by mapping the past, present, and future of the retail industry and consumption using content analysis of secondary data. The authors pay special attention to the effect of the current Covid-19 crisis on the future development of the retail industry. In the findings of this chapter, the authors recognize institutional logics changes in organizing the position of retailing as a connector of customers and producers, and the authors suggest blockchain to be an emerging new institutional order.

Abstract

This chapter will introduce the concept of the gig economy. It begins with a brief discussion of technological changes and their impact on the workforce and labour market, demonstrating how the trend shifts towards the gig economy. It then examines the trends that are influencing this transformation and discusses various perspectives and the attractiveness of the gig economy for workers and businesses. This chapter will also discuss the gig economy, platform economy, digital platform, and gig worker categories. It concludes with a brief discussion of some of the opportunities, issues, and challenges associated with the gig economy.

Abstract

Presents an exploratory field research on all hospitals in Singapore, highlighting the different routes hospitals have adopted in pursuing their corporate quality journey for the new millennium. In general, both continuous improvement and innovation‐based approaches have generated cost and time savings and helped to streamline work processes. However, the initial survey results show that innovation‐based programs require a longer time frame for implementation, are more prone to resistance to change and suffer from program failure. Also, large hospitals and public hospitals are more inclined to implement innovation based approaches while medium‐sized hospitals tend to use continuous improvement as a medium for quality improvement.

Abstract

Purpose

This study aims to examine the impact of COVID-19 on tourism and hospitality small and medium-sized enterprises (SMEs) in an emerging country located in Latin America and identifies service innovation strategies adopted by these firms to survive a prolonged crisis.

Design/methodology/approach

A qualitative investigation was conducted drawing on a framework of imposed service innovation. Data were obtained from in-depth interviews with owners/managers of 20 SMEs in the hospitality and tourism sector in Chile.

Findings

Findings show that the effect of COVID-19 on SMEs includes a decline in demand due to lockdowns and restrictions, with minimal government support. Tourism and hospitality SMEs developed different service innovation strategies to confront the crisis, and several businesses were even able to exploit new opportunities for future growth.

Originality/value

The effect of COVID-19 and SMEs' service innovation strategies to confront a prolonged crisis is a topic that is largely unexplored, particularly in the tourism and hospitality sector. The findings contribute to the literature on emerging markets, crisis management and SME innovation in tourism and hospitality. The findings provide managerial implications for SME managers, governments and policymakers.
