为研究隔震技术加固砌体结构房屋的可行性及适用性,以一栋层数和高度均超限的既有多层砌体结构教学楼为对象,详细介绍隔震加固设计全过程,并利用软件ETABS对隔震加固后的结构进行分析。结果表明,隔震加固后,砌体结构的自振周期明显延长... 为研究隔震技术加固砌体结构房屋的可行性及适用性,以一栋层数和高度均超限的既有多层砌体结构教学楼为对象,详细介绍隔震加固设计全过程,并利用软件ETABS对隔震加固后的结构进行分析。结果表明,隔震加固后,砌体结构的自振周期明显延长,地震响应显著降低;变形集中于隔震层,隔震层以上结构层间位移角在设防地震作用下远小于2倍弹性层间位移角限值,在罕遇地震作用下远小于4倍弹性层间位移角限值,满足了预定的抗震性能目标;隔震支座的水平位移和拉/压应力也远小于规范限值。隔震层以上结构X、Y向减震系数最大值分别为0.301和0.379,均小于0.4,结构构造措施可按比设防烈度降低一度确定,解决了结构层数和高度超限问题。 展开更多

It is driven by the need to improve English classroom instruction for university students in China (Wen, 2016). It is also motivated by the aspiration to enhance the quality of foreign language education in other similar pedagogical contexts outside China. A volume of research has been done by Wen Qiufang and her research team, to formulate the theory of POA and to test its effectiveness in classroom pedagogy (e.g. Wen, 2016, 2015; Yang, 2015; Zhang, 2015). At the moment, the POA is still at an early stage of theory building and almost all empirical research is done in the Chinese context. In order to improve the quality of this theory and to make it intelligible to the international academic community, a one-day symposium was held in Beijing Foreign Studies University on May 15, 2017. The symposium was entitled 'The first international forum on innovative foreign language education in China: Appraisal of the POA'. In the forum, leading experts in applied linguistics were invited to discuss the strengths and weaknesses of the POA and the directions for its future development. The symposium was the first attempt for the POA research team to discuss its latest work with international scholars. This Viewpoint section collects the responses of four experts who participated in the symposium, listed in alphabetical order. The collection of articles covers three topics related to the POA: its pedagogical application, its use for teacher training, and its research. Alister Cumming is Professor Emeritus and the former Head of the Centre for Educational Research on Languages and Literacies, University of Toronto, Canada. His article focuses primarily on POA research as an exemplary case of design-based research. Rod Ellis is Research Professor in the School of Education at Curtin University, Australia. He discusses POA in terms of pedagogy, teacher training and research, with both critiques and constructive suggestions. Paul Kei Matsuda is Professor of English and Director of Second Language Writing at Arizona State University, the writed states. He responds to POA from the perspective of an expert researcher and teacher of L2 writing. Charlene Polio is Professor and Associate Chair in the Department of Linguistics & Germanic, Slavic, Asian & African Languages atMichigan State University, the writed states. She conceptualises POA as a useful method to address some issues in pre-service teacher development. Overall, the articles in this section are insightful and reader-friendly. They are not only useful for the development of POA in particular, but may also be valuable to a broad range of researchers as they touch upon pertaining issues, as well as emerging topics, in the field of applied linguistics. We therefore find it necessary to make them accessible to a wide readership. 展开更多
