Abstract

Purpose

This research proposes a viable method of slab and shore load computation for the partial striking technique utilized in high-rise construction projects to optimize the use of horizontal formwork. The proposed Partial Striking Simplified Method (PSSM) is designed to be utilized by industry practitioners to schedule the construction operations of casting floors in order to control the formwork costs incurred throughout the completion of a project.

Design/methodology/approach

The article presents the PSSM for calculating slab and shore loads in multi-story building construction. It introduces the concept of “clearing before striking,” where shore supports are partially removed after a few days of pouring fresh concrete. The PSSM procedure is validated through numerical analysis and compared to other simplified approaches. Additionally, a user-friendly Python program based on the PSSM procedure is developed to explore the capability of the PSSM procedure and is used to study the variations in slab load, shoring level, concrete grade and cycle time.

Findings

The study successfully developed a more efficient and reliable method for estimating the loads on shores and slabs using partial striking techniques for multi-story building construction. Compared to other simplified approaches, the PSSM procedure is simpler and more precise, as demonstrated through numerical analysis. The mean of shore and slab load ratios are 1.08 and 1.07, respectively, which seems to have a slight standard deviation of 0.29 and 0.21 with 3D numerical analysis. The Python program developed for load estimation is effective in exploring the capability of the proposed PSSM procedure. The Python program's ability to identify the floor under maximum load and determine the specific construction stage provides valuable insights for multi-story construction, enabling informed decision-making and optimization of construction methods.

Practical implications

High-rise construction in Indian cities is booming, though this trend is not shared by all the country's major metropolitan areas. The growing construction sector in urban cities demands rapid construction for efficient utilization of formwork to control the construction costs of project. The proposed procedure is the best option to optimize the formwork construction cost, construction cycle time, the suitable formwork system with optimum cost, concrete grade for the adopted level of shoring in partaking and many more.

Originality/value

The proposed PSSM reduces the calculation complexity of the existing simplified method. This is done by considering the identical slab stiffness and identical shore layout for uniform load distribution throughout the structure. This procedure utilizes a two-step load distribution calculation for clearing phase. Initially, the 66% prop load of highest floor level is distributed uniformly over the lower interconnected slabs. In the second step, the total prop load is removed equally from all slabs below it. This makes the load distribution user-friendly for the industry expert.

Abstract

Purpose

The purpose of this study is to examine the subnational regional dimension of exports by small and medium-sized enterprises (SMEs) in India, one of the prominent emerging economies or “rising powers”.

Design/methodology/approach

To understand the forces driving the variation in subnational region’s share in international business of rising power SMEs, an analytical conceptual framework on regional export advantage (REA) was formulated based on the review of relevant theoretical and empirical literature. The model was estimated for Indian states using the most appropriate and recently developed econometric technique of fractional logit model.

Findings

The paper provides evidence that the emergence of exports by rising Indian power SMEs is geographically limited to a few select regions/states. Southern Indian states alone accounted for half of exports from SMEs in the organized manufacturing sector during 2000-2008, followed by Western India. The REA analysis has brought to the fore that regional stock of technological knowledge, availability of skill, port facilities, urban areas and foreign direct investment stocks are crucial factors determining states’ share in SME exports across technological subcategories. However, the size and sophistication of local demand continue to influence states’ efforts at enhancing exports by SMEs, at least those belonging to the medium- and high-technology categories.

Research limitations/implications

The proposed empirical framework could be extended to include institutional and political economy factors. Its application to subnational regional shares in total exports by all firms taking into account fixed effects for regions may be another feasible line of future research.

Practical implications

Empirical findings recognize that appropriate strategies by subnational policymakers are important for a region to achieve a higher contribution in national SME exports. Subnational policy measures aimed at upgradation of regional technological assets and skill base through the promotion of technology clusters and R & D of local firms, facilitation and creation of better industry-university linkages and investments in education and training institution may help the states to gain higher export advantage.

Originality/value

This paper provides new analytics and insights into the role of subnational spaces in the internationalization of rising power SMEs from India and serves to contribute to the extant international business research that is predominantly occupied with “nation” as the unit of location.

Abstract

Purpose

Crowdfunding, an alternative funding source to support entrepreneurial initiatives, has increasingly attracted the attention of scholars. However, knowledge of the drivers and outcomes of crowdfunding is currently scant. This study thus presents a review of the extant literature on new ventures soliciting crowdfunding.

Design/methodology/approach

The authors conducted a systematic literature review (SLR) of peer-reviewed articles, identifying and thematically analyzing 58 publications.

Findings

The thematic analysis revealed six main themes: a) founders and crowdfunding, b) signaling and crowdfunding, c) digitalization and crowdfunding, d) outcomes, e) geography and crowdfunding and f) success factors. In addition, crucial research gaps are identified to guide future research.

Practical implications

Beyond classifying the material on the basis of the thematic analysis and identifying potential future research avenues, the study has main implications. The authors detailed how crowdfunding, as a source of entrepreneurial funding, differed from other funding sources and explored entrepreneurial challenges that may be encountered in managing crowdfunding campaigns. The findings may thus help in the design of crowdfunding campaigns and serve educators in various disciplines when teaching and training participants on designing and promoting crowdfunding campaigns.

Originality/value

After identifying and integrating results from relevant articles on crowdfunding, the authors explained dominant themes in the literature and proposed a conceptual framework wherein the authors highlight factors that influence crowdfunding outcomes. The authors highlight the increasing relevance of crowdfunding for new ventures and elucidate avenues for future research.
