three-phase research program has been undertaken in order to develop a better understand of PMOs. This paper presents the research strategy, the overall program, and the results of the first phase of the research.
This paper contributes to the ongoing work and debate on the value of project management, accomplishing this through an empirical investigation of practitioner perceptions on the relative value of different project management practices and their potential to contribute to improved project performance. This investigation is based on a large-scale survey of 753 project management practitioners. This paper aims to answer four questions relating to the value of project management. By identifying the most valued practices, practitioners and organizations can identify their priorities when developing their project management competencies. This can also guide the profession in selecting priorities for future development. When choosing priorities to develop and implement, organizations can look to the tools that practitioners identify as most valuable, as having the most potential for increased contribution to project performance, and as presently under-utilized. In order to fully understand the nature of project management practices, and the mechanisms through which these create value, researchers must better clarify the distinction between the project phases and project processes. These findings can help project management professionals in selecting priorities for future development.
This paper describes a new method of analysis and design for steel frames with concrete or masonry infilling walls subjected to in-plane forces. The method is based on data generated from previous experiments as well as results from a series of nonlinear finite-element (NLFE) analyses. The method accounts for elastic and plastic behavior of infilled frames considering the limited ductility of infill materials. The proposed method predicts the strength and stiffness of infilled frames as well as the infill diagonal cracking load. The method also allows for the major practical imperfections, such as lack of fit and shrinkage ofthe infil!. Variations, such as infill aspect ratio and beams having different strength and stiffness from the columns, are accounted for and it is concluded that the behavior of frames with pin or semirigid joints can also be predicted. The method is further developed to model multistory infilled frames as braced frames, replacing the infills by equivalent diagonal struts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
