Floor response spectra in RC frame structures designed according to Eurocode 8

© 2015 Springer Science+Business Media Dordrecht Nonstructural components (NSCs) should be subjected to a careful and rational seismic design, in order to reduce the economic loss and to avoid threats to the life safety, as well as what concerns structural elements. The design of NSCs is based on the evaluation of the maximum inertia force, which is related to the floor spectral accelerations. The question arises as to whether Eurocode 8 is able to predict actual floor response spectral accelerations occurring in structures designed according to Eurocode 8. A parametric study is conducted on five RC frame structures in order to evaluate the floor response spectra. The structures, designed according to Eurocode 8, are subjected to a set of earthquakes, compatible with the design response spectrum. Time-history analyses are performed both on elastic and inelastic models of the considered structures. Eurocode formulation for the evaluation of the seismic demand on NSCs does not well fit the numerical results. Some comments on the target spectrum provided by AC 156 for the seismic qualification of NSC are also included

Comments on Caddo Settlement Pattern and Culture Identity

This discussion will be based primarily upon Schambach\u27s work and observations on Caddo habitation settlements in the Great Bend area of Southwestern Arkansas. Schambach believes that the basic Caddo settlement pattern is that of a dispersed hamlet configuration clustered around a specific civic-ceremonial center. This settlement configuration is based upon archaeological work in the Great Bend area which conforms to a stylized but highly accurate map drawn from an inhabited historic Caddo village compound presumably near the Hatchel Mound site (41BW3) on the west bank of the Red River in Texas

From the western classics to the world: secondary music teachers' changing attitudes in England 1982 and 1998

Two parallel samples of secondary music teachers in England, taken from 1982 and 1998, reveal similarities and differences in their evaluations and uses of twentieth and pre-twentieth century Western classical music, folk music, popular music, jazz and ‘world’ music. Least change occurs with relation to folk and pre-twentieth century classical music; most with relation to popular and world musics. The status of classical music is high in each of the two time periods, but in different ways. By the end of the century, teachers’ views of musical value have overall, shifted radically towards more global perspectives, and their classroom approaches include far more integrated practical work involving performing, composing and listening, with an emphasis on cross-stylistic comparisons and musical universals

Participatory Monitoring of Community-Based Rehabilitation and other Disability- Inclusive Development Programmes: the Development of a Manual and Menu

Purpose: This paper describes a three-year research project leading to the development of the CBR Monitoring Manual and Menu (MM&M). The MM&M is a practical toolkit that meets the needs of CBR managers and stakeholders, and is consistent with the philosophy of CBR and community-based disability-inclusive development. It is designed to produce meaningful and locally useful information and data, based on international data standards where possible, to enable aggregation at regional, national and international levels. Methods: Five complementary workstreams of research were carried out from 2011 to 2014: 1) literature review and analysis; 2) participatory action research with CBR stakeholders; 3) analysis and refinement of validity of concepts and structures; 4) consultation and review; and 5) synthesis of results. This article documents the method and key results of each of the five workstreams, and the lessons learned along the way. Results: The MM&M is now freely available on-line at http://sydney.edu.au/health-sciences/cdrp/projects/cbr-monitoring.shtml. Collaboration among members of the development team continues, chiefly via an on-line group to which new members have been welcomed. Conclusion and Implications: At the time of writing, the MM&M is the only international monitoring product, known to the authors, that consciously sets out to reflect both a ‘bottom- up’ and ‘top-down’ perspective of monitoring information and data. To achieve this for a complex programme such as CBR, and to align with its principles, it was essential to use a multi-component and multi-stage strategy for tool development, involving a diverse multidisciplinary team includingcollaboration with CBR stakeholders
