新框架结构强度与堆砌形状研究.docVIP

题 目 新框架的结构强度与堆砌形状的研究 关 键 词 结构强度 堆砌的形状 杆件截面形状 抛投方式 框架平面 摘 要： 由框架群结构组成可以知道，框架形状，框架杆件形状，框架群内的空隙率、框架体的数量将直接影响到框架群的透水和阻水性能，制约着框架群的减速效果，而且在工程实际运用中，单个框架群单位体积所包含的框架体数量的多少，直接影响到工程的投资。对单位体积的框架群，其内部框架体的数量多少将直接影响到框架群的空隙率，而单个框架体的的大小又会直接影响到内部框架体数量的多少，且四面六边透水框架在使用过程中，存在被水流冲击而移位的可能性，使框架群达不到理想的堆砌效果，影响其功能。故此次我们所设计的新的框架结构是原先的四个四面六边透水框架所组成的一个新的框架。我们主要从两点出发研究这个新的框架结构。一是研究它的结构强度，另一个是由这个新的框架结构如何堆砌成合理的形状。对于结构强度，我们又分为4个方面进行研究；对于如何堆砌成合理的形状，我们从多个方面研究一个合适的框架群的规模到底是如何的，从中说明一个形状的合理性。 参赛队号: 2099 所选题目: A 题 Abstract Composed of a frame structure can know, the shape of a frame, the frame shape, the number of voids within the framework of the group, the frame rate will directly affect the frame group of water and water resistance, restricts the deceleration effect framework group, and in engineering practice, the amount of the frame body single frames per unit volume contains, directly affects the project investment. Per unit of volume frame group, the number of the internal frame body will directly affect the space frame group rate, and a single frame body size will directly affect the amount of internal frame body, and the six side of permeable frame in use process, the possibility exists of water impact and shift, the frame group could not reach ideal stack effect, affecting its function. A new framework so we designed a new framework consisting of the original four surrounded by six side permeable frame. We mainly study the new frame structure from two. One is the structural strength of it, another is by this new framework structure how piled into the reasonable shape. For the structural strength, we divide the research into 4 aspects; how to build a reasonable shape, we studied from many aspects of an appropriate framework for group size is how, justify a shape from. Key words: structural strength pile shape bar cross-srction shape throwing patterns the plane of frame
