Abstract

Abstract Composite sections are found to be a novel technique in modern day scenario of construction. This stands tall than the ordinary and conventional type of constructions. Columns as a structural element play a vital role in structural frame. This research comments on the behavior of composite columns. The main objective of this study is to analyze the behavior of steel-encased concrete composite columns as experimentally under axial compression and the mode of failure under ultimate failure and yield point. The steel-concrete composite system combines the formability and rigidity of reinforced concrete with the ductility and strength of structural steel to meet the demand for earthquake-resistant constructions. Three specimens were chosen for this study: one was a composite column, the other two were ordinary RC columns and structural steel columns. The raw materials' natural properties are assessed. As a result, material testing for cement, fine aggregate, and coarse aggregate was completed, as well as a concrete mix design. A comparative analysis of the local and post-local buckling behavior of different composite sections has been studied and the column sections have been designed according to Eurocode 4 (ENV 1994) to determine the plastic resistance of the section. These three specimens underwent compression test and the results are tabulated and compared. The corrosion resistance and fireproof nature (resistance to fire at higher temperatures) that are transmitted into the member are related to the steel being encased within the concrete. These are the two major drawbacks of any steel construction combined with an earthquake-resistant structure. Rather than a traditional steel construction, earthquake structures benefit from this type of load handling capabilities. The portion can be used before it completely collapses if proper design factors are taken into account.

复合柱性能及极限强度有限元分析

摘要复合截面是现代建筑中的一种新技术。这比普通和传统类型的结构更高。柱作为一种结构构件，在结构体系中起着至关重要的作用。本文对组合柱的受力性能进行了评述。本研究的主要目的是分析钢-混凝土组合柱在轴压作用下的试验性能，以及在极限破坏和屈服点下的破坏模式。钢-混凝土组合体系将钢筋混凝土的成形性和刚度与结构钢的延性和强度相结合，以满足抗震建筑的要求。本研究选取了三个试件：一个是组合柱，另两个是普通RC柱和结构钢柱。对原材料的自然特性进行了评估。因此，完成了水泥、细骨料和粗骨料的材料测试，以及混凝土配合比设计。对不同复合材料截面的局部和局部后屈曲行为进行了比较分析，并根据欧洲规范4（ENV 1994）设计了柱截面，以确定截面的塑性阻力。这三个试样进行了压缩试验，并将结果制成表格进行比较。传递到构件中的耐腐蚀性和防火性（在较高温度下的耐火性）与混凝土中包裹的钢有关。这是任何钢结构与抗震结构相结合的两个主要缺点。与传统的钢结构不同，地震结构受益于这种类型的荷载处理能力。如果考虑到适当的设计因素，该部分可以在完全塌陷之前使用。

期刊介绍： Science and Engineering of Composite Materials is a quarterly publication which provides a forum for discussion of all aspects related to the structure and performance under simulated and actual service conditions of composites. The publication covers a variety of subjects, such as macro and micro and nano structure of materials, their mechanics and nanomechanics, the interphase, physical and chemical aging, fatigue, environmental interactions, and process modeling. The interdisciplinary character of the subject as well as the possible development and use of composites for novel and specific applications receives special attention.
