Abstract: Culture-led urban regeneration is an influential planning strategy in Western countries, which is to maintain the city character while enhancing the overall competitiveness of the city through the construction of cultural development to meet the urban environment of the new cultural needs. For the moment, the rapid development of social economy of Chongqing has accelerated its urbanization process. As one of the available land stock resources of urban, existing-blocks need updating to meet the new environmental requirements immediately because of physical and functional decline. So it is essential to consider the strategy of culture-led urban regeneration synthetically. It can not only maintain the social network structure and neighborhood relationship of the existing-blocks to continue urban context while improving its image, but also provide a sustainable competitive city. Taking existing-blocks in Chongqing as the main research object, analyze the current characteristics of the existing-blocks, then put forward the culture-led planning strategy from macro, micro and mid-scale to adapt the development of Chongqing existing-blocks by drawing on the experience at home and abroad.

Abstract: Based on the overall urban-rural development, through analyzing the issues and their causes during the exploration of Chongqing new countryside construction, the paper discuss a new mode of “urban-rural field and park” planning in countryside construction. Taking Qianqiu Village as a case on study, the article proposes the planning mode which is coordinating of “three types of plans” as guarantee, interacting primary with tertiary industry as guidance, combining function and industry to efficient land use, taking a cluster layout of "House - Park - Field" to integrating rural landscape. So as to resolve the abuse caused by urban-rural spatial differentiation, integrate urban-rural living, production, and promote urban-rural development.

Abstract: Everyone wants to know the future society. So many people suppose the future by various methods. This study supposes the future city and building by analyze the neologisms and S.F. movie with Maslow’s hierarchy of needs. We select the 12 movies and search the remarkable scenes in the view point of architecture or city. Then, we analyze the character of scene by Maslow’s hierarchy of needs. And also we select & analyze the neologisms with same method. Movies and neologisms are not same in expression philosophy. Because movie want to earn money but, neologism want to talk the society. As a result, physiological needs or love/belonging needs are low element but safety, esteem and actualization needs are frequently appeared.

Abstract: Urban flooding due to climate changes, dam breaking and drainage systems being overwhelmed by rainfall causes a huge loss to mankind civilization every year all over the world. This work aims to minimize the flooding damage by optimally design the building location and interspace. The velocity, water pressure and the height of water are considered as the main factors to reduce the flooding damage. The multi-objective optimization is implemented by combing several techniques, including Design of Experiment (DOE), Response Surface Method (RSM) and the Genetic Algorithm (GA). The proposed methodology is validated with a case study on the topography of ESTP Cachan.

Abstract: Field tests for indoor thermal environment of Tibetan-style dwellings of different materials in Shangri-La in winter were carried out from the perspective of physical environment of buildings, and more specifically, the indoor temperature of Tibetan-style dwellings with rammed earth walls and brick walls as well as the surface temperature of building envelope were tested and comparatively analyzed. The test results show the current situations and features of indoor temperature changes of Tibetan-style dwellings of different materials, which may provide a basis for improving the thermal environment of Tibetan-style dwellings.

Abstract: The green space of students’ living area is an important part of Chinese university campus. It has a close relationship with students’ daily life, study and amusement. In recent years, as the campus has been being newly-built or rebuilt, green spaces in students’ living area have been greatly improved. However, a survey shows that many students are not satisfied with these green spaces. In order to find out problems existing in landscape design of these green spaces, this paper, from the perspective of environmental psychology, investigated and analyzed students’ behaviors and corresponding psychology in these green spaces by taking Chang’an campus of a university in Xi’an as a case. On this basis, this paper attempts to conclude experiences and lessons in designing green spaces of students’ living area, and hopes to provide some useful references for the design of campus landscape.

Abstract: Earth-dwelling caves are a kind of traditional housing with unique and typical native characters. The construction of these caves is mostly based on the experiences of native craftsmen, merely passing down and developing orally without forming systematic theories and with little word-recording. However, they embody deep mechanical principles and structural implication worth long protection. At present, the earth-dwelling caves of thousands of years are rapidly disappearing and the techniques of construction are facing the danger of being lost as well, which is bound to bring about the loss of an architectural culture. This paper tries to approach the folk construction techniques of these traditional earth-dwelling caves, which will have a special significance to the passing-down and protection of such a cave housing culture.

Abstract: This paper shows us the concept of remodeling traditional cave-houses in frigid climate of Loess plateau, and the optimization design through study and practice on a common housing project in Yan’an has proved that designers should pay attention to the regional characteristics in both function and space. To achieve the goal of creating high comfort with low consumption, economic efficiency with less earthwork, designers should also aim at incorporating the specific local climate with architectural adaptability by combining the domestic low-cost technology with active design optimization.

Abstract: A system is developed for simulating the collapse behavior of reinforced concrete frame structures from seismic loading. The purpose for developing this system is that the whole process from elastic-plasticity to collapse is modeled in the analysis. Consequently, the collapse mode, the collapse duration, the distribution of the debris after collapse and other information can be obtained. The numerical analysis is based on the distinct element method. The element shape is assumed to be rectangular solid, which is based on the cross section of the structural members. The elements are connected by dummy springs. The impact action among concrete blocks after the connecting springs fail is taken into account by the impulse models of impact, which are derived from the results of the experiments and the numerical tests. A comparison between a shaking-table test and the analysis is presented, which shows that the results of the simulation are in good agreement with the results of the experiment.

Abstract: Spring pendulum with single-frequency excitation can be expressed in a group of complicated nonlinear equations. Bifurcation of the spring pendulum with single-frequency is studied in this paper, feedback controllers are designed, analysis method is used to obtain the control equation of excited system, and the relationship function between control parameters and bifurcation is gained. This acts as an implementation of feedback control method to saddle-node bifurcation control, and also brings average method to numerical calculation of multiple-degree-of-freedom nonlinear system.
