Conceptual framework for live capture and reuse of project knowledge

Abstract: The concept of knowledge management (KM) is now familiar to the construction industry, and various attempts are being made to develop tools and techniques for the effective management of knowledge in the industry. This paper addresses the ‘live’ capture of construction project knowledge, which is as yet, an elusive goal in KM efforts. It describes an approach to achieve this using a combination of techniques and tools including learning histories, collaborative learning, project extranets and workflow management. This proposed methodology also specifies the incorporation of a ‘project knowledge file’ which will form the basis of knowledge capture during the execution of a project, an integrated workflow system and a project knowledge manager. The intention is to ensure the currency and relevance of the knowledge captured, prevent the ‘re-invention of the wheel’, and facilitate innovation, increased agility, better teamwork and supply chain integration, and improved project performance.

Seismic behavior of high-performance fiber reinforced composite frames

Abstract: The paper explores the possibilities to use a High-Performance Fiber Reinforced Concretes (HPFRCs) for design of seismic resistant cost-effective and durable buildings. Composite frame buildings are made through selective use of different HPFRCs: Slurry Infiltrated Mat Concrete (SIMCON), Slurry Infiltrated Fiber Concrete (SIFCON) and High Strength - Lightweight Aggregate Fiber Reinforced Concrete (HS-LWA FRC) which further minimizes dead and seismic loads. The first part of the paper briefly describes used HPFRCs and proposed composite building system consisted of composite columns, beams and specially designed fuses that connect the two. In the second part of the paper the results of the nonlinear static analysis of an isolated composite beam as well as of the nonlinear dynamic analysis of a whole four-story example composite building are presented. The response in terms of forcedisplacement relationships and rotational ductility factors as well as in terms of base shear, top displacements and global damage index histories is compared to the response of an identical classical four-story building made of reinforced concrete.
