本文從混凝土的熱物理特性和熱傳導的基本概念出發,討論了混凝土結構中的溫度分佈規律,分析了高層建築結構中溫度變形和溫度內力產生的原因,並介紹了高層建築結構中溫度變形和溫度內力計算的實用方法,包括連續化法,迭代法及有限單元法。The strength is a main mechanics performance index of the concrete. it has always been a focus of material scientific research of concrete. models about mechanics characteristic of concrete were mostly the understanding based on material macroscopical level of concrete in the past. its main characteristic turns the material ideal with heterogeneous, nonuniform nature into the even, continuous body and carry on modeling. this kind simplified and met project practice ' s demands to a certain extent, but it is difficult to study the influence produced toward strength of material of structure of the microcosmic or the mescoscopic within the concrete material with this kind of method
以往有關混凝土力學特性的模型大多是基於混凝土材料宏觀層次的認識,其主要特點是把具有多相、非均勻性質的材料理想化為均勻、連續體進行建模,這種簡化盡管在一定程度上滿足了工程實踐的需要,卻難以用這種方法來研究混凝土材料內部微觀或細觀結構對材料強度所產生的影響,不能說明材料內部結構如孔結構變化時強度的變化規律,也不能用於指導如何改進材料的組成和微觀結構而達到提高混凝土強度的目的。The dissertation refers to comparatively full literatures in the field of vsc, and the development history and characteristics of vsc are summarized, and the elementary concepts, elementary definitions, elementary properties, elementary principles and design methods are particularly introduced, and the causes of the chattering phenomenon are systematically analysed, and the study status of the chattering phenomenon and the main methods to eliminate the chattering are elaborated. for the deficiencies of traditionary methods, three improved methods are developed, which are improved exponent reaching law solution, variable boundary layer solution and the solution by adding an auxiliary continuous control term. for uncertain linear systems, an adaptive fuzzy integral variable structure control stategy ( afivsc ) is put forward to eliminate the chattering around the sliding plane, which introduces fuzzy logic to soften the non - linear discontinuous sig nal in the control variable and utilizes adaptive theory to adjust output membership function according to how much the uncertainty of the system is
比較全面地查閱了關于變結構控制理論的文獻,總結了滑模變結構控制的發展歷史和特點,詳細介紹了變結構控制的基本概念、基本定義、基本性質、基本原理以及設計方法;系統分析了變結構控制系統抖振產生的機理,並闡述了國內外目前對抖振問題的研究現狀以及消除抖振的主要方法;針對傳統抑制和消除抖振方法的不足,改進了傳統方法,得到了三種新的消除抖振的方法? ?即改進的指數趨近律法、可變邊界層法和附加連續項法;針對不確定性線性系統,在變結構控制策略中引入模糊邏輯和自適應理論來消除滑動平面上的抖振,提出了一種自適應模糊積分變結構控制方案( afivsc ) ,利用模糊邏輯來柔化控制量中非線性不連續部分,採用自適應理論,根據系統不確定性大小在線調整模糊輸出量的隸屬函數,另外,鑒于模糊控制本質上是有靜差的,所以本文選擇了帶積分項的切換函數,由於積分項的存在使系統較正為無靜差系統。Abstract : to facilitate the design, teaching and research of asphalt pavements, the article founded the models of displacement and tensile stress of three - layer system by using separation of variables, analysis and synthesizer. based on the analysis of common pavement structures and their equivalent conversion, the regression formulas of displacement and tensile stress are obtained successfully, furthermore the formulas applied in multi - layer system are checked. a great number of results of regression formulas show good accuracy for engineering application and theory research
