Fast Nonlinear Analysis of Traditional Chinese Timber-Frame Building with Dou-Gon

ABSTRACT

This article presents a study of the applicability of fast nonlinear analytical (FNA) models in predicting the global response of Chinese traditional timber-frame building with Dou-Gon under seismic excitation. Efforts are made to overcome challenges in establishing simplified calculation models, and the corresponding dynamic equations are derived considering the mechanical behavior of sliding column root, mortise-tenon joint and Dou-Gon (bracket sets). Furthermore, nonlinear time-history analysis is conducted under different seismic excitations. Through a verification study, a good correspondence is obtained with previous shake-table test results. Seismic response analysis is also conducted to investigate the energy dissipation of column root sliding, mortise-tenon joint, and Dou-Gon. Subsequently, peak responses of column root and roof under increased values of peak ground acceleration (PGA) are also analyzed. And then, seismic isolation ability and damping characteristics of the model are discussed.     

Cottages and the Country House: Power,Paternalism and Protest in Elsecar

In the period c.1790 to 1870, the small rural hamlet of Elsecar, near Barnsley, was transformed into an extensive industrial village, with a thriving economy based on iron and coal. Most of this development was instigated, controlled and financed by the local landowners, the 4th and 5th Earls Fitzwilliam. As well as being passionately interested in the practicalities and potential of industrial development, the Earls also looked to the welfare of their workers, providing a wealth of benefits including pensions, sick pay and purpose-built industrial housing. Using a historical approach based on a variety of source material, this paper explores the Earls’ provision of workers’ housing as a way in which to consider wider themes of power, control, inequality and resistance as they were expressed both in the physicality of the houses themselves, and in the cultural meanings which were attributed to them by contemporary observers. The paper argues that workers’ housing functioned as a visible embodiment of power relationships within Elsecar and, because of this, it continues to have a significant resonance in the modern world.     

实事求是与制度建设

当前,制度性缺陷是影响坚持实事求是思想路线的突出问题.因而,要编织严密的制度之网,将制度保障机制建设与提高干部队伍自身素质相结合,将外在的硬性约束与内在的软性约束相结合,确保实事求是思想路线得到贯彻落实.     

日常消费空间中的情绪产生与作用机制——基于南京的实证研究

本研究引入消费者行为学的"认知-情绪-行为"模型，并加入空间要素建立整体框架，采用结构方程模型与质性研究相结合的方法，探讨消费空间中影响消费者情绪产生的因素以及情绪对居民生活满意度的作用。研究表明，积极情绪的产生主要受到个人价值观的鲜明度、消费场所物质环境的宜人度和消费场所中社会交往的深度影响；消极情绪的产生主要受到个体经济地位和个人价值观的鲜明度影响；积极情绪与消极情绪均显著影响消费者的生活满意度，积极情绪会导致较高生活满意度的产生。本研究从情绪的角度阐释消费空间和人的关系，是从微观尺度上对情绪地理学研究的新探索，同时也为城市消费空间研究与规划提供了人本主义的新视角。
