Preliminary Report on Seismic Testing of a Full-Scale Six-Story Steel Building

A full-scale six-story steel building was constructed and tested as part of the U.S./Japan Cooperative Earthquake Research Program Utilizing Large Size Testing Facilities. The program was jointly funded by the Ministry of Construction of Japan and the United States National Science Foundation. The overall objective of the program is to improve seismic safety in practice and to determine the relationships among full-scale tests, small-scale tests, component tests and analytical studies. The full-scale building was 15m square in plan and measured 22.38m from the test floor to the top of the roof girders. It was tested as a concentric braced frame; repaired and tested as an eccentric braced frame; tested as a moment frame; and finally, tested with cladding and other nonstructural elements installed. The tests were conducted using the pseudodynamic testing technique which simulated actual seismic loadings. This preliminary report describes the full-scale building and the testing program and presents preliminary results and conclusions.National Science Foundation Grants CEE 83-12656, CEE 82-06200, ECE 8511315, CEE 82-07521, ECE 85-15419, and CEE 83-0068

Social media such as Facebook, Twitter and YouTube are often seen as political game changers. Yet little is known of the effects of social media on local politics. In this paper the Social Media Participation Model (SMPM) is introduced for studying the effects of social media on local political communities. The SMPM aims to explore the relationship between Social Media Participation and Community Participation. The model comprises four constructs: Social Media Choice, Social Media Use, Sense of Community and Community Engagement. The design of the case study was based on the SMPM and took place among the members and parties of the Enschede council, from a large municipality in the Netherlands. Social media participation levels were measured and compared with the Social Media Indicator (SMI). A negative correlation between Social Media Use and Sense of Community has been discovered. However, we could not find a causal effect that explains this correlation. To analyze the effects in more detail, we show directions for further improvement of the model
