The main advantage of castellated beam is the increasing of bending capacity caused by the increasing of inertia moment of steel section due to the increasing of depth of the steel section. In addition, some people argue that the opening section of castellated beam become an additional advantage in terms of aesthetics view. In general, there are three opening variations that are very often used in construction, which are hexagonal opening, circular opening, and diamond opening. Many researches have been done to compare the performance of castellated beam with various opening but only focusing on the behavior of castellated beam subjected to monotonic loading. Therefore, in this research, a review of the behavior of castellated beam with various opening subjected to quasi-static cyclic loading was carried out in order to find out which is better performance from the opening variations. A finite element analysis was conducted to find out the behavior of castellated beam with three variations of opening. A simple beam subjected to quasi-static loading using displacement control technique was considered in this research. The result shows that the castellated beam with diamond opening has a better performance compared to the other openings (hexagonal opening and circular opening).

A steel-concrete composite slim beam, with its steel section encased in a concrete slab, provides a composite steel-concrete floor construction with minimum depth and high fire resistance. It has become popular in multi-storey steel buildings throughout Europe in recent years and also been used in some projects in China. For the structural engineer, it is critical to understand the behavior of composite slim beam in the sagging moment region. In this paper, the bending capacity and flexural stiffness of the composite slim beams in sagging moment region are investigated theoretically. Meanwhile, the stiffness and bending capacity are given by Finite Element Analysis (FEA). The experiment of a simply supported beam has been carried out in order to validate the theoretical results.

Castellated Beam

Castellated beam is escalation in vertical bending stiffness, simple carrier provision and appealing look. But one effect of presence of Web beginning will be the development of varied local results. Castellated beams are metal beams with web openings and that they benefit its benefit because of its multiplied depth of phase without any extra weight. To analyze the conduct of castellated metal beams having an I-shaped go-element. Analysis is carried from beam with two factor load and genuinely supported assist condition.

Abstract For semiconductor lasers, fiber and optical source alignment is crucial for maintaining high optical transfer efficiency. Traditional optoelectronic manufacturing, production of butterfly packages for example, involves laser welding of fiber mountings followed by a tedious realignment procedure to reverse thermally-induced distortions. An alternate technique, laser hammering, entails manipulation of the fiber to light alignment through deformation of the fiber housing with high precision laser beams. A detailed understanding of the material and mechanical behavior, characteristics, and dynamic response is vital to successfully apply an efficient controller that can choose an optimal weld pattern based on a light to fiber misalignment. Modeling provides an effective means to determine an optimal fiber alignment control technique. Modeling is difficult due to the dynamic thermal-mechanical coupling of these processes. This paper presents the preliminary results of a series of parametric studies regarding thermal-mechanical coupling models employed in finite element analysis in order to assess the behavior and dynamic response of representative materials and geometries under various boundary conditions. Fiber ferrule and ferrule housing dimensions affect resistance to bending and torsion, which in turn governs the magnitude of the displacement field. The models are then applied to geometries typical of alignment fixtures used in laser diode packages. The effects of laser energy deposition location and resolution as well as assumed boundary and initial conditions are also discussed. Convection and the small variations in ferule geometry do not have a strong effect on the overall response.

A general method for integrating genetic algorithms within a commercially available finite element (FE) package to solve a range of structural inverse problems is presented. The described method exploits a user-programmable interface to control the genetic algorithm from within the FE package. This general approach is presented with specific reference to three illustrative system identification problems. In two of these the aim is to deduce the damaged state of composite structures from a known physical response to a given static loading. In the third the manufactured lay-up of a composite component is designed using the proposed methodology.
