Model experimental researches of simply-supported floor and four-corners bearing floor have been done on this new kind of floor system in this paper. The experiment results show that the floor system has good mechanical property such as high bearing capacity, big rigidity and good tensility. A theoretical method is presented in this paper that the stiffening-ribbed-hollow-pipe girderless floor can be analyzed by being converted equivalently to orthotropic solid slab. It is indicated that the method is correct and reasonable according to the contrast between theoretical calculated results and experimental measured results. The theoretical results coincide with the measured results well.展开更多

To deepen the understanding of the experience in the spatial place, we shift the origin of environmental landscape design from "design environment" to "design experience". The essence of experience is to arouse perception, such as senses, emotions, spirits, thinking, action to participate, among which "form, space, quality" as the carrier of landscape sculpture's place spirit and experience co-form a complete spatial place imagery of landscape sculpture. Place experience makes people able to experience a more detailed and richer world, these construction activities bring innovation consciousness with inner vitality, and detail the means of man observing the world while seeking a pluralistic world.展开更多
