分析研究课题混凝土材料是一种复合性材料，由粗细骨料、胶合料和其它不同类型的添加剂组成。钢纤维混凝土是在混凝土基体中再掺入适量的钢纤维制成的一种混凝土基复合材料。混凝土作为一种优良的工程材料，其使用量越来越大，应用领域遍及工业与民用建筑工程、水利工程、交通工程、军事工程、海洋工程等土木工程领域。由于混凝土作为建筑材料存在着抗拉强度低、韧性差等固有弱点，随着高强混凝土的应用，抗压强度不断提高，这一弱点更加突出。还有混凝土材料本身所固有的孔、裂缝及其它原始缺陷使其存在延性差、脆性大等缺点，这在很大程度上影响和阻碍混凝土材料的进一步发展。为了从根本上改善混凝土这种优良建筑材料在阻裂和延性等方面的先天不足，在混凝土中掺入乱向分布、弹性模量较高的短细钢纤维是改善混凝土性能的有效措施。钢纤维混凝土是在混凝土基体中掺入适量钢纤维和外加剂所形成的一种混凝土复合材料，在混凝土凝固过程中，钢纤维可以有效地减少收缩裂纹的数量，并减少裂纹间距。在承受荷载过程中，钢纤维具有阻止裂缝发展的作用，跨越裂缝和靠近裂缝尖端的纤维，能将过高的应力传递给裂纹的上下表面，缓和应力集中的程度，推迟或抑制裂缝的扩展。它兼具普通钢纤维混凝土的延性和韧性好的特征。钢纤维的掺入改变了混凝土的破坏形态，使脆性材料表现出延性性能，扩大了混凝土的应用范围。随着经济的发展，新的结构形式对混凝土性能提出更高的要求，钢纤维高强混凝土这种新型建筑复合材料的应用领域必将不断扩大。2.

有限元【内容摘要】钢纤维混凝土作为一种新型复合材料，已广泛的应用于建筑、桥梁、隧道、水利等工程中。目前，对于钢纤维混凝土的低应变速率静力试验以及高应变速率冲击试验已有较多研究成果，但对于地震荷载作用下中等应变速率范围内（10-4 /s10-2 /s）的试验研究还有待深入，混凝土材料的动态特性是抗震研究中的薄弱环节。为此，本文系统地进行了钢纤维混凝土在中等应变速率响应范围内的6 种纤维含量（0%、1%、1.5%、2%、2.5%、3%）、4 种周围压力（0MPa、8MPa、16MPa、24MPa）、2 种基体强度（C40，以SFCA 表示；C30，以SFCC 表示）的单轴、常规三轴的单调与重复加卸荷等多种动态压缩试验，累计完成252 个试件的加载试验。同时，利用医用CT 扫描技术得到了混凝土内部细观数据图像，结合图像数字处理技术对混凝土内部细观结构进行了重建，并在此基础上进行了混凝土材料的有限元数字劈拉试验。具体工作内容如下。（1）研究了单向应力状态下各种钢纤维含量和强度等级的钢纤维混凝土在应变速率为10-3 /s 时的强度特性和变形特性。（2）系统地分析了三向应力状态下各种钢纤维含量、围压和强度等级的钢纤维混凝土在应变速率为10-3 /s 时的峰值应力、峰值应变、应力-应变曲线、弹性模量、泊松比、韧度比、八面体应力空间的分布等多种指标参数，得出了各种指标参数与纤维含量、围压大小、强度等级等相互的影响关系。（3）采用等应变增量的重复完全加卸荷试验，并对其应力-应变曲线的包络线特征、峰值应力、峰值应变、卸载曲线特征、残余应变、再加载曲线特征、横向应变特征、共同点轨迹线特征等进行了分析。（4）根据地震时程曲线的特征，进行了钢纤维混凝土两种不同频率的非等幅循环荷载试验，比较了不同频率循环荷载下的强度特性和变形特性。（5）基于CT 扫描得到的图像，结合图像数字处理技术，对混凝土的真实细观结构进行了重建，并将其导入有限元软件之中，建立了更能准确表征混凝土细观非均质性的二维数值试件，进行了几种不同情况的劈裂对比试验；采用对CT 扫描的DICOM 格式原始数据调用的方式，建立了混凝土或钢纤维混凝土真实细观结构的三维模型，较好的体现了混凝土的非均质性，为进一步在细观层次上研究混凝土内部的破坏机理奠定了一定的基础。【论文标题】

钢纤维轻骨料混凝土具有轻质高强、韧性优、保温隔热等显著优点。将钢纤维和天然浮石轻骨料混凝土结合起来成为钢纤维轻骨料混凝土，钢纤维轻骨料混凝土兼有钢纤维混凝土的韧性高和轻骨料混凝土质量轻等优点。 本论文通过掺入钢纤维、高效减水剂、优质引气剂及矿物掺合料配制了三种强度等级(LC30，LC35，LC40)的浮石轻骨料混凝土。本文对这种新型的多相复合混凝土材料的力学性能开展初步研究，分析了钢纤维体积率变化对轻骨料混凝土的立方体抗压强度、轴心抗压强度、弹性模量、劈裂抗拉强度和抗折强度的影响。试验结果表明，钢纤维的加入能明显提高轻骨料混凝土的抗拉强度和抗折强度；掺入钢纤维使轻骨料混凝土的抗压强度有一定程度的提高，增长幅度不大，但抗压韧性却有很大改善，使钢纤维轻骨料混凝土裂而不散；钢纤维轻骨料混凝土的弹性模量随钢纤维体积率的增大有一定提高，表观密度略有增加。 本文最后探讨了钢纤维对轻骨料混凝土的阻裂增韧机理，并对进一步的研究工作提出了建议。本文的试验结果可为钢纤维轻骨料混凝土的研究与应用提供试验依据和理论依据。4.2 外文文献信息检索4.2.1 Engineering Villagea.检索步骤：进入广东工业大学图书馆外文数据库Engineering VillageQuick search；b.检索过程：检索条件: (steel fibers

title】: Computational Materials Science【Issue date】：April 2008【Pages】：259-265【Language:】：English【Document type】：Journal article (JA)【Abstract】: An irregular distribution of steel fibers in fresh concrete results in a complex structure. This causes changes in the behavior of hardened concrete members, even in the response of those produced under the same conditions. Therefore, it is fairly difficult to predict the performance of steel fiber added lightweight concrete. This study investigates the usability of artificial neural network (ANN) to estimate the compressive strength of such concrete. For this purpose, normal strength lightweight concrete with 350, 400, and 450 kg/m3 cement dosages are produced. The Dramix RC-80/0.60-BN type steel fibers are added to each specimen at the dosages of 0, 10, 20, 30, 40, 50, and 60 kg/m3 leading to a total of 126 cylindrical samples of the size 150 300 mm. The compressive strength of the specimen is then experimentally determined. The parameters considered for the ANN inputs are the amounts of steel fiber, water, water-cement ratio, cement, pumice sand, pumice gravel, and super plasticizer. The test results obtained from the ANN are compared with the multi linear regression technique based on mean square error, mean absolute error, and correlation coefficient criteria. The study concludes that the ANN predicts the compressive strength of steel fiber added lightweight concrete better than does the MLR. 2007 Elsevier B.V.

The obvious material softening character of SFRC after compression-shear failure, indicated by the bilinear shear softening curve, can be observed from test data. The compression-shear strength of SFRC is proven to be the function of compressive stress and steel fiber contents. However, the enhancing effect from compressive stress and steel fiber content is independent. According to the test data, the calculation formula of compression-shear strength was proposed and verified with the finite element method.4.2.2 EBSCO检索平台a.检索步骤：进入广东工业大学图书馆外文数据库EBSCO检索平台选择数据库Academic Source Premier高级检索；b.检索过程：检索条件: TX steel fibers concrete and TX compressive strength 时间：2008-2008c.检索结果：得到4条记录，筛选摘录其中2篇文摘。【标 题】Stress-Strain Behavior of Steel Fiber-Reinforced Concrete in Compression.【作 者】Bencardino, Francesco1 f.bencardinounical.itRizzuti, Lidia2 l.rizzutistrutture.unical.itSpadea, Giuseppe3 g.spadeaunical.itSwamy, Ramnath N. 4R.N.Swamysheffield.ac.uk【作者单位】1Assistant Professor, Dept. of Structural Engineering, Univ. of Calabria, Rende, CS, 87036 Rende, Italy 2Ph.D. Candidate, Dept. of Structural Engineering, Univ. of Calabria, Rende, CS, Italy 3Professor, Dept. of Structural Engineering, Univ. of Calabria, Rende, CS, Italy (corresponding author) 4Professor Emeritus, Dept. of Mechanical Engineering, Univ. of Sheffield, S13JD Sheffield, U.K【来 源】Journal of Materials in Civil Engineering; Mar2008, Vol. 20 Issue 3, p255-263, 9p, 2 Color Photographs, 1 Diagram, 4 Charts, 3 Graphs【主 题 语】STRUCTURAL design；REINFORCED concrete；STRAINS & stresses；MATERIALS - Compression testing；FIBER-reinforced concrete；CONCRETE。【关 键 字】Compression tests；Compressive strength；Concrete, reinforced；Fiber reinforced materials；Softening；Steel fibers；Stress strain relations。【摘 要】Good structural design demands high quality experimental data and reliable modeling of the mechanical properties of the constituent materials. Although several theoretical models and much experimental data on the behavior of fiber-reinforced concrete in compression are available in published literature, there are considerable reservations on the general applicability of these models for design. This paper presents the results of tests in compression of steel fiber-reinforced concrete carried out according to standard procedures, and a critical evaluation of the models proposed to define the stress-strain behavior in compression. The tests reported were carried out on cylindrical specimens of plain and steel fiber-reinforced concrete with fiber volume of 1, 1.6, and 3%. To evaluate the reliability of the models available in literature, a critical comparative study was carried out between the experimental data and the various proposed theoretical stress-strain relationships. It is shown that while many of the models showed good agreement with test results from which the model equations were derived, there was no such good agreement when the models were applied to other published test data.

The main objective of this work is to obtain a more ductile high strength concrete produced by using both silica fume and steel fiber. Two types of steel fibers with aspect ratios (fiber length/fiber diameter) of 65 and 80 were used in the experiments and volume fractions of steel fiber were 0.5% and 1%. Additions of silica fume into the concrete were 0%, 5%, 10% and 15% by weight of cement content. Water/cement ratio was 0.38 and the reference slump was 12020mm. Slump test for workability, air content and unit weight tests were performed on fresh concretes. Compressive strength, splitting tensile strength and flexural strength tests were made on hardened concrete specimens. Loaddeflection curves and toughness of the specimens were also obtained by flexural test performed according to ASTM C1018 standards. Flexural tests on beam specimens were achieved using a closed loop deflection-controlled testing machine. The use of silica fume increased both the mechanical strength and the modulus of the elasticity of concrete. On the other hand, the addition of steel fiber into concrete improves toughness of high strength concrete significantly. As the steel fiber volume fraction increases, the toughness increases, and high values of aspect ratios give higher toughness. The toughness of high strength steel fiber concrete depends on silica fume content, the fiber volume fraction and the fiber aspect ratio.
