摘 要:嘉绒藏区碉楼作为我国重要的历史文化瑰宝,一旦发生地震灾害,结构倒塌,会给我国优秀文化传统的传承和发展造成重大损失。为了更好地保护碉楼,我们就必须要清楚知道碉楼结构性能。为此,文章基于ADINA有限元分析程序,对嘉绒藏区碉楼的简化计算模型进行了结构静态分析。其研究内容主要有:(1)计算模型的建立:利用ADINA有限元分析软件,建立了嘉绒藏区碉楼模型。(2)碉楼结构静态分析:碉楼属于凹凸不规则、扭转不规则。且负一层和顶层为刚性楼板,一层和二层为柔性楼板。

Abstract: As an important historical and cultural treasure in Jiarong Tibetan area, once the earthquake disaster occurs and the structure collapses, it will cause great loss to the inheritance and development of the outstanding cultural tradition in our country. In order to better protect the bunker, we must clearly understand the structure and performance of the blockhouse. For this reason, based on the ADINA finite element analysis program, the paper has carried on the structural static analysis to the simplified calculation model of the blockhouse in Jiarong Tibetan area. The main contents of this paper are as follows: (1) Establishment of the calculation model: using ADINA finite element analysis software, the model of the blockhouse in Jiarong Tibetan area is established. (2) Static analysis of the structure of the blockhouse: the blockhouse belongs to the concave and convex irregular and the torsional irregular. The first floor and the top floor are rigid slabs, and the first and second floors are flexible slabs.
Keywords: Jiarong Tibetan area bunker; ADINA software; shear stress
前言
藏族作为我国西部最为古老的部族之一,为我们留下了众多文化遗产。这些文化遗产具有较高的历史与学术价值,广大学者去研究与保护也就具有比较重要的意义。此项研究有助于提高当地人民生活水平,可以对少数民族建筑的文化传承起到积极促进作用。碉楼建筑是嘉绒藏族物质文化遗产和非物质文化遗产重要的载体。它们也承载藏羌民族的思想理念、审美情趣、宗教信仰和生活习俗,呈现出万千的姿态和迥异的风格,是它们为人类留下的一份弥足珍贵的文化遗产,具有科学价值、历史价值、文化价值和艺术价值。
1 碉楼建模理论分析
碉楼是一种石砌体结构形式的建筑,和石砌体建筑特点比较相似。所用材料基本和石砌体相符,只是碉楼的块石形状各异。……
