【摘要】：SRC結(jié)構(gòu)由于其剛度大、抗震性能好等特點(diǎn),得以廣泛應(yīng)用。SRC結(jié)構(gòu)就是在鋼筋混凝土截面內(nèi)部配置型鋼后所形成的鋼-混凝土組合結(jié)構(gòu)形式,兩者協(xié)同工作,充分發(fā)揮各自的性能優(yōu)勢(shì),使得SRC結(jié)構(gòu)成為理想的抗震結(jié)構(gòu),尤其適用于高層建筑和大跨度建筑。但是,其施工工序繁多、結(jié)構(gòu)連接繁雜等突出特點(diǎn),制約了這種結(jié)構(gòu)的推廣,使SRC結(jié)構(gòu)優(yōu)異的綜合性能得不到充分發(fā)揮。因此專家提出了一個(gè)新概念——預(yù)制裝配型鋼混凝土結(jié)構(gòu)形式(PSRC結(jié)構(gòu))�？善駷橹�,國內(nèi)的設(shè)計(jì)規(guī)范、設(shè)計(jì)標(biāo)準(zhǔn)僅針對(duì)SRC梁,沒有關(guān)于PSRC結(jié)構(gòu)方面的設(shè)計(jì)指導(dǎo),相關(guān)研究也鮮有可聞。因此,對(duì)PSRC試件抗震性能和抗震設(shè)計(jì)方法的研究刻不容緩。本文提出V型截面預(yù)制腹板的PSRC梁,對(duì)其進(jìn)行擬靜力試驗(yàn)研究,填補(bǔ)PSRC結(jié)構(gòu)在這種截面形式下的研究空白,為PSRC結(jié)構(gòu)理論發(fā)展提供相關(guān)的科學(xué)支撐。由于地震作用下PSRC抗震性能是最為紛繁復(fù)雜的,所以本文采取擬靜力試驗(yàn)的方法,對(duì)V型預(yù)制腹板PSRC試件抗震性能展開初步研究。主要工作如下:(1)以剪跨比、混凝土強(qiáng)度作為控制參數(shù),對(duì)4根預(yù)制型鋼混凝土梁進(jìn)行低周反復(fù)荷載下的試驗(yàn)研究,研究其受力機(jī)理、破壞形態(tài)和破壞特征。(2)通過理論分析的方式對(duì)試驗(yàn)現(xiàn)象和數(shù)據(jù)進(jìn)行分析總結(jié),研究各設(shè)計(jì)控制參數(shù)下,其抗震性能的變化規(guī)律,綜合其滯回性能、剛度退化規(guī)律、強(qiáng)度衰減規(guī)律、延性性能和耗能能力等指標(biāo),系統(tǒng)分析各試件的抗震性能,根據(jù)現(xiàn)象分析PSRC梁疊合面的受力性能,探究影響抗震性能的主要因素。(3)總結(jié)本文研究成果和需要改進(jìn)的地方,并提出V型預(yù)制腹板PSRC梁的加強(qiáng)構(gòu)造措施布置,對(duì)其后續(xù)研究進(jìn)行展望。
[Abstract]:Because of its high stiffness and good seismic performance, SRC structure is widely used in the form of steel-concrete composite structure formed after the reinforced concrete section is configured with section steel, and the two structures work together. The SRC structure is an ideal seismic structure, especially for high-rise buildings and long-span buildings, by giving full play to their respective performance advantages. However, its outstanding characteristics, such as numerous construction procedures and complicated structural connections, restrict the popularization of this kind of structure and make the excellent comprehensive performance of SRC structure not fully play. Therefore, a new concept of precast assembly steel reinforced concrete (SRC) structure is put forward by experts. But up to now, the domestic design code, the design standard is only for SRC beams, there is no design guidance on the PSRC structure, and the relevant research is rarely heard. Therefore, it is urgent to study the seismic performance and seismic design method of PSRC specimen. In this paper, PSRC beams with V-shaped prefabricated web plates are proposed, and the quasi-static test is carried out to fill the blank in the research of PSRC structures in this form, and to provide relevant scientific support for the development of PSRC structure theory. Because the seismic behavior of PSRC is the most complicated under earthquake action, the seismic behavior of V-shaped prefabricated web PSRC specimens is studied preliminarily by quasi-static test method in this paper. The main work is as follows: (1) with shear span ratio and concrete strength as control parameters, four precast steel reinforced concrete beams are tested under low cyclic cyclic loading, and their mechanical mechanism is studied. Through theoretical analysis, the experimental phenomena and data are analyzed and summarized, and the variation law of seismic performance under various design control parameters is studied, and the hysteretic performance and stiffness degradation law are synthesised. According to the strength attenuation law, ductility and energy dissipation capacity, the seismic behavior of each specimen is systematically analyzed, and the mechanical behavior of the composite plane of PSRC beam is analyzed according to the phenomena. The main factors affecting seismic performance are discussed. (3) the research results and the improvement are summarized, and the arrangement of strengthening measures for V-shaped precast web PSRC beams is put forward, and the future research is prospected.
