A review of the practical relevance of IS strategy scholarly research

While studies suggest that IS strategy is an important topic for practitioners, in-depth explorations of the potential practical relevance of this research area are lacking. In this paper, we develop a multidimensional framework of potential practical relevance and use it to conduct a multimethod descriptive review of 109 IS strategy papers published over the past 10 years in top IS journals. The framework contributes to the IS literature by synthesizing various characteristics that make a research project conducive to being practically relevant. The review highlights how IS strategy research has offered the potential for practical relevance in the past and recommends opportunities to increase this, especially in the digitalization era

Equivalent Imperfections In Arched Structures

Abstract There are currently three design methods to verify the in-plane buckling of an arched structure: substitute member method, the method of equivalent imperfection with recommendations for arched bridges, and the equivalent unique global and local initial imperfection method (EUGLI), which uses the critical elastic buckling mode as an imperfection. The latter method is included in the EN 1993-1-1 cl. 5.3.2 (11) since 2002; however, to this day it is neither utilized in the design practice nor is it incorporated in ordinary structural analysis software. The main purpose of this article is to show the application of the proposed methods in a step-by-step manner to the numerical example considered and to compare these design methods for various arched structures. Verification of the in-plane buckling of an arch is explained in detail.</jats:p

Buckling mode as an imperfection in arch structures

An Equivalent Unique Global and Local Imperfection (sometimes referred as an ‘EUGLI’ imperfection) is an equivalent imperfection that has a shape affine to the form of a critical elastic buckling mode. This design method, in its generalized form designated for the frame structures, is included in the EN 1993-1-1 cl. 5.3.2 (11) since 2002. To this day however, it is neither known in the design practice, nor it is incorporated in the common structural analysis software. This design method is suited for verification of members (beam-columns) with nonuniform cross-section and/or non-uniform axial compressive force. It can be used for general 2D and 3D frame structures. A good example for this complicated structure is an arch bridge. A main problem is that the amplitudes for these imperfections are not experimentally established. Yet a procedure proposed by the same author (as the author of the ‘EUGLI’ imperfection) can be used to obtain a design value of amplitude, which is derived from the substitute member method. Purpose of this article is to show the application of proposed method on numerical example and its comparison with two other design methods. Verification of the in-plane buckling of an arch will be carried out

Very low seismicity areas in Slovakia and comparison of seismic risk in Central European Countries

Very low seismicity areas in Slovakia and comparison of seismic risk in Central European CountriesA parametric study concerning the importance of very low seismicity for Slovakia is introduced. Analyses were performed for ordinary buildings such as family houses, residential brick buildings, residential panel buildings and high-rise buildings. Both horizontal wind and seismic actions were analysed and compared in detail for all the regions and conditions in Slovakia.</jats:p
