Vibration of steel framed floors due to running

Ford, Cassandra January 1900 (has links)
Master of Science / Department of Architectural Engineering and Construction Science / Bill Zhang / Vibration has been a consideration in many types of structures, and as the advancement of technology has allowed steel and concrete sections to become lighter, vibration has become more of a consideration in the design of structures. This report focuses on occupant induced vibration of steel framed floors due to running as the vibration source. The history of vibration analysis and criteria in structures is discussed. However, lack of research and experimentation on running as the source of vibration exists; therefore, the history section focuses on walking as the source of vibration. The current design criteria for vibration of steel framed floors in the United States of America is the American Institute of Steel Construction (AISC) Design Guide 11: Vibrations of Steel Framed Structural Systems Due to Human Activity. This design guide discusses vibration due to walking, running, and rhythmic activities as well as gives design criteria for sensitive occupancies and sensitive equipment. In order to apply the Design Guide 11 analysis procedure for running as the source of vibration, the Kansas State University Chester E. Peters Recreation Complex is used as a case study. The recreation complex includes a 1/5-mile running track that is supported by a composite steel framed floor. Based on the Design Guide 11 criterion, the running track is deemed acceptable. Lastly, this report discusses remedial procedures in the case of annoying floor vibration specific to floors that have running as a source of vibration. In addition, areas of further research are suggested where running is a source of vibration on steel framed floors.

Comparison of blood lactate levels between treadmill running and over-ground running during incremental tests : A study on elite male runners

Blom, Oa January 2020 (has links)
Tests to evaluate runners' aerobic capacity aiming to design training programs are often performed on a treadmill, while the training mainly takes place on over-ground surfaces. Studies have shown that different degrees of inclination on treadmills can compensate for the differences in heart rate (HR) response between running on treadmills and over-ground surfaces. The purpose of the study was to test whether the blood lactate concentration (BLC) differs between over-ground running and treadmill running at matched HR, and if so; can inclination of the treadmill be adjusted to generate equal BLC at matched HR? Eight male elite runners performed three incremental running tests where HR and BLC were measured; on a flat treadmill at six running velocities, on a running track at six velocities equal to the HR at test one, and on a treadmill at a fixed HR on different inclines (0°, 0.3°, 0.6°, 0.9°, 1.1° and 1.5°). The results revealed a non-significant trend indicating that over-ground running yields higher BLC at matched HR than treadmill running, and that 0.3° incline on treadmill correlated best with over- ground running. This study demonstrates a clear tendency of higher BLC at a given HR when running on an over-ground surface in comparison to running on a treadmill. Furthermore, a 0.3° incline on a treadmill is suggested to compensate for the difference in BLC at matched HR, between running on a treadmill and on an over-ground surface. However, more research with a larger sample size is needed to conclude and generalize the results.

APPOLO - Towards integrated urban education in Pretoria : a multi-functional vertical primary school

Du Plessis, Dewald 30 November 2010 (has links)
The Apollo Project investigates the recent establishment of numerous private educational institutions in the inner city of Pretoria. It identifies the need for adequate urban educational facilities and explores the use of existing buildings as schools. An existing educational cluster is identified at the eastern edge of the inner city, defined by Church, Du Toit and Pretorius Streets, and Nelson Mandela Drive. This city block and the ones surrounding it contain numerous primary, secondary and tertiary educational institutions in a predominant industrial/automotive precinct. An urban design framework is proposed for the precinct. It is envisioned that the precinct may be developed as a mixed-use urban educational campus. Within the existing city block and the urban framework proposal, the Apollo Centre, located on the corner of Church-and Du Toit Street, is selected for an adaptive re-use intervention. The proposed use is an urban primary school. The Apollo project investigates current pedagogical trends, which informed a concept that is largely defined by the idea of contextual learning within a vertical structure. Transparency and integration of education with the urban environment is at the core of the proposal. The traditional notion of horizontal education is explored in a vertical manner. The existing structure is analyzed and a position taken regarding the adaptive re-use process that informs the design. Precedent Studies include existing schools within the inner city of Pretoria as well as local and international schools. The process of converting the Apollo Centre into a primary educational facility, that shares its resources on a cross-programming basis, is explored in a series of proposals. The numerous explorations are considered in their various aspects, as well as their relationship to the whole, which then leads to a final design proposal. Key areas of the proposed Apollo Primary School will finally be resolved technically. A conclusion summarizes the author’s thoughts on the result of the project. / Mini Dissertation (MArch(Prof))--University of Pretoria, 2010. / Architecture / unrestricted
