【摘要】：隨著人類對建筑物視覺效果要求的不斷提高,玻璃越來越廣泛地運(yùn)用到各類建筑物當(dāng)中,其優(yōu)良的透光性能契合了大眾對建筑的審美需求。玻璃的安全使用性能是其在設(shè)計過程中所必須考慮的極為重要的問題。近年來,由于玻璃破裂所引起的人員傷亡及財產(chǎn)損失屢見不鮮,其破壞的突然性以及玻璃殘渣極易傷人的性質(zhì)對于結(jié)構(gòu)工程師而言是巨大的挑戰(zhàn)。本文旨在研究玻璃強(qiáng)度的測定方法以及如何解決玻璃脆性破壞的問題,對實(shí)際工程設(shè)計具有較強(qiáng)的指導(dǎo)意義。介紹了各個國家對于玻璃強(qiáng)度測定的實(shí)驗標(biāo)準(zhǔn),主要為美國規(guī)范ASTM、英國規(guī)范BS EN、俄羅斯規(guī)范以及中國規(guī)范。從實(shí)驗樣本以及加載環(huán)境兩方面比較了不同國家規(guī)范對于玻璃大面強(qiáng)度以及邊緣強(qiáng)度測定的差別,為我國補(bǔ)充和完善玻璃強(qiáng)度測定規(guī)范做了參考。從平面內(nèi)受力和平面外受力兩個方面綜述了夾膠玻璃后破壞強(qiáng)度的研究方法和現(xiàn)狀。提出了三階段模型與塑性鉸線法相結(jié)合的理論模型來計算夾膠玻璃后破壞強(qiáng)度,該方法物理意義明確、計算方法簡便,針對不同支承方式、不同幾何形狀的夾膠玻璃均可適用,與實(shí)驗結(jié)果吻合程度較好。運(yùn)用此模型系統(tǒng)研究了玻璃板厚度,膠層厚度,玻璃板跨度、支承方式以及膠層材料等因素對于夾膠玻璃后破壞強(qiáng)度的影響;計算三角形、矩形以及六邊形夾膠玻璃的后破壞強(qiáng)度,比較不同多邊形的夾膠玻璃后破壞強(qiáng)度的大小;計算菱形夾膠玻璃的后破壞強(qiáng)度,分析相鄰邊夾角對于菱形夾膠玻璃后破壞強(qiáng)度的影響。闡述了夾膠玻璃中玻璃與膠層之間的粘結(jié)機(jī)理。運(yùn)用商業(yè)軟件ABAQUS以及黏聚力單元對玻璃與膠層之間的粘結(jié)特性進(jìn)行了有限元模擬,分別比較了黏聚力單元中初始剛度、初始破壞強(qiáng)度以及破壞的斷裂能對玻璃和膠層之間粘結(jié)性能的影響,為日后進(jìn)一步深入研究玻璃與膠層粘結(jié)特性提供了可行的思路。
[Abstract]:With the increasing demands of human beings on the visual effects of buildings, glass is more and more widely used in all kinds of buildings, and its excellent transmittance can meet the aesthetic needs of the public. The safety performance of glass is an important problem in the design process. In recent years, the casualties and property losses caused by glass rupture are common. The sudden destruction and the nature of glass residue are a great challenge to structural engineers. The purpose of this paper is to study the measuring method of glass strength and how to solve the problem of glass brittleness failure, which is of great significance for practical engineering design. The experimental standards for the determination of glass strength in various countries are introduced, including ASTM, BS ENN, Russia and China. The differences between different national codes for the determination of glass strength and edge strength are compared from two aspects of experimental samples and loading environment, which provides a reference for the supplement and perfection of glass strength measurement standards in China. The research methods and present situation of post-failure strength of glass-clamped glass are reviewed from two aspects: in-plane force and out-of-plane force. A theoretical model combining the three-stage model and the plastic hinge method is proposed to calculate the post-failure strength of the glass-clamped glass. The physical meaning of the method is clear and the calculation method is simple, which can be used for different support modes and different geometric shapes of glass-clamped glass. The results are in good agreement with the experimental results. By using this model, the influence of glass plate thickness, rubber layer thickness, glass plate span, support mode and rubber layer material on the failure strength of glass-clamped glass is systematically studied, and the triangle is calculated. The post-failure strength of rectangular and hexagonal glass-clamped glass was compared, and the post-failure strength of rhombohedral glass-clamped glass was calculated. The influence of the angle of adjacent edges on the failure strength of rhombic glass-clamped glass was analyzed. The bonding mechanism between glass and rubber layer in glass-intercalated glass is described. Using commercial software ABAQUS and cohesion element, the bonding characteristics between glass and adhesive layer are simulated by finite element method, and the initial stiffness of cohesion element is compared respectively. The influence of the initial failure strength and fracture energy on the bond properties between the glass and the adhesive layer provides a feasible way to further study the bonding properties between the glass and the adhesive layer in the future.
