The main purpose of the current research work is to achieve an economical cold formed steel castellated beam with diamond castellation with limited buckling. In this way, to study the behavior of cold formed steel castellated beam with diamond castellation by the provision of different methods of placing the stiffeners for the sections is an main scope of the work. It can be achieved through this paper, which gives an Numerical, Analytical Study and Experimental investigation on the performance of cold-formed steel Castellated beams with Diamond Castellation shape. Perforations in web has been carried out to know its structural behaviour as simply supported beam under pure bending. The castellated steel beams with perforated web epitomize a new inventive which has occurred in the past span for the short- and medium length of beams. The Cold-Formed Steel provides a substantial weight reduction of these beams with castellation, compared to the hot-rolled beams. The Castellated Beam has made with 2 mm thickness CFS Steel, used all over the Beam. In the study, the Castellated Beam has been performed with three types of Stiffener Designs at web of the Beam. Beam with intercept Stiffeners plates at web has used. Both stiffened and unstiffened Castellated beam (Beam with Parallel, Perpendicular and intercept Stiffeners) were tested for numerical and experimental Testings. Finally, numerical analysis using ABAQUS 6.11 results are evaluated and the experimental results were confirmed with the results obtained from the finite element analysis. Based up on the numerical analysis and experimental investigation the different failure and buckling modes of the proposed beams has been studied and the load carrying capacity of beams has been predicted.

当前研究工作的主要目的是实现一种经济的冷弯钢制带齿形梁的钢制带齿梁，屈曲有限。通过这种方式，通过提供不同的截面加劲肋放置方法来研究具有菱形齿形的冷弯钢齿形梁的行为是工作的主要范围。通过本文可以实现这一点，并对具有菱形Cast形的冷弯steel形钢梁的性能进行了数值分析和实验研究。已对腹板进行穿孔，以了解其结构行为，即在纯弯曲下的简单支撑梁。带孔腹板的带钢腹梁是过去短梁和中等长度梁中出现的一项新发明的缩影。与热轧梁相比，冷弯型钢可显着减轻这些带有cast形的梁的重量。ell形梁由厚度为2毫米的CFS钢制成，在整个梁中使用。在研究中，在梁腹板上采用三种类型的加劲肋设计进行了Cast堡梁设计。在腹板使用了带有截断加强板的梁。对加筋和未加筋的Cast形梁（平行，垂直和截取加劲肋的梁）都进行了数值和实验测试。最后，评估了使用ABAQUS 6.11结果进行的数值分析，并通过有限元分析获得的结果证实了实验结果。
