【摘要】：隨著近年來經(jīng)濟(jì)的飛速發(fā)展,建筑行業(yè)也進(jìn)入了高速發(fā)展的時(shí)期,而鋼筋混凝土板作為土木工程結(jié)構(gòu)中的一種基本構(gòu)件,被廣泛的應(yīng)用到各個(gè)領(lǐng)域。而在混凝土應(yīng)用最多的建筑行業(yè)里,大多數(shù)情況下用到的都是薄板結(jié)構(gòu),涉及到厚板領(lǐng)域并不多見。近10年來我國(guó)地鐵行業(yè)發(fā)展迅速。由于地鐵車站的特殊使用環(huán)境,造就了其對(duì)鋼筋混凝土板與眾不同的特殊要求,在地鐵車站中鋼筋混凝土板的厚度要遠(yuǎn)遠(yuǎn)大于一般建筑物中鋼筋混凝土板的厚度。龍述堯、姜琛通過研究得出薄板和中厚板的分界線一般取厚跨比為0.1,中厚板和厚板的分界線一般取厚跨比為0.2。學(xué)術(shù)界對(duì)于薄板的研究較已經(jīng)取得了眾多成果,但是對(duì)于厚板的研究還有所不足,在設(shè)計(jì)中往往仍然采用薄板理論。本文基于Reissner中厚板理論,系統(tǒng)的研究分析開洞對(duì)中厚板受力性能的影響。著重分析了洞口尺寸、洞口形狀、洞口位置以及板厚等四大影響因素。通過運(yùn)用大型通用有限元軟件ABAQUS對(duì)各個(gè)因素建立多組模型進(jìn)行對(duì)比分析。通過對(duì)比混凝土板件的應(yīng)力、應(yīng)變和橫向剪切應(yīng)力在各個(gè)因素影響下的變化情況,總結(jié)其在統(tǒng)一的徑厚比、厚跨比、開洞比情況下的變化規(guī)律,將之運(yùn)用于其它厚板情況。最后基于實(shí)際工程,將工程中所需開設(shè)的較大洞口歸納為三種,針對(duì)不同的洞口分別建立完整的有限元模型,在整體的雙層框架結(jié)構(gòu)中研究洞口對(duì)中厚板件受力性能的影響,驗(yàn)證前文所得部分結(jié)論。
[Abstract]:With the rapid development of economy in recent years, the construction industry has also entered a period of rapid development. As a basic component of civil engineering structure, reinforced concrete slab has been widely used in various fields. However, in the construction industry where concrete is used most of the time, thin plate structure is used in most cases, and it is rare in the field of thick slab. China's subway industry has developed rapidly in the past 10 years. Because of the special application environment of subway station, the special requirement of reinforced concrete slab is created. The thickness of reinforced concrete slab in subway station is much larger than that of reinforced concrete slab in general building. Long Shuyao and Jiang Chen obtained that the dividing line between thin plate and medium thick plate is generally 0.1, and that between plate and thick plate is 0.2. Many achievements have been made in the research of thin plate in academic circles, but the research on thick plate is still insufficient, and the theory of thin plate is still used in the design. Based on Reissner's plate theory, the effect of hole opening on the mechanical behavior of plate is studied systematically. The size, shape, position and thickness of orifice are analyzed. By using the large-scale finite element software Abaqus, the various factors are compared and analyzed. By comparing the variation of stress, strain and transverse shear stress of concrete plate under the influence of various factors, this paper summarizes the variation law of concrete slab under the uniform ratio of diameter to thickness, thickness to span ratio and ratio of opening to hole, and applies it to other thick slab cases. Finally, based on the actual engineering, the large openings needed in the project are classified into three types, and the complete finite element models are established for the different openings, and the influence of the openings on the mechanical behavior of the plate parts is studied in the whole double-deck frame structure. Verify some conclusions obtained above.
