In aircraft structural applications, the manufacturers normally use curved laminated beam structures while designing their internal structures. At some point, the composite structure may be subjected to bending which may compress or flatten its composite structure. This may result in the generation of the interlaminar stresses, taking the thickness direction of the composite. For one to understand the reason behind the occurrence of the delamination failure. It is vital to study such interlaminar stresses being the major contributors in the process. This may prompt the need to conduct studies for other forms of stresses such as the in-plane which may be related to the beam curvature pre-existence (Nath, 2017).
The decision on the strength and size the structural members
According to Suzuki (2016), structural engineering considers bending moment as a fundamental concept to be considered in understanding the constituting activities in establishing and handling a beam. Considering a frame having a vertical load positioned at the centre of a beam, may cause the considerable level of bending, which may however not be experienced with a column. Considering the effect of the external force in both the beam and column can be used as a guideline in designing them to withstand the shear and moment forces which they are most likely to experience. Columns may be susceptible to high shear forces in case of an earthquake hence are designed to withstand such lateral forces. With reference to the points of connection between a beam and the vertical columns, it is important to note that the maxim shear force occurs around the support. This makes it easy to understand the level of the occurrence of such forces at different points of a beam.
Nath (2017) added that a relevant experiment can be carried out to demonstrate that the member's sizes are designed to accommodate the bending moment. This may be observed in the use of both a beam and a column. Considering a complete load envelope, all members will tend to have a maximum demand for the capacity ratio in case of shear or bending. This explains why the axial forces are not commonly used buildings where as bending is used in most cases.
Determines the level of reinforcement required in a concrete structure
Suzuki (2016) argued that the nature of moment demonstrates to cause compression and tension simultaneously in a given section. There is some level of compatibility achieved in the use of concrete and steel. The concept of the use of the two materials together in a building is due to their nearly equal linear expansivity. The two have a common quality of achieving a desirable level of comparison. Steel further has an additional quality in tension besides the mere compression they have in common. The application of steel may, however, undermine the expected reinforcement in a structure owing to the size of the rebar material which makes it buckle easily. A common mistake in this instance can be using a wrong amount and wrong place for the reinforcement which has the potential of causing failures. It is therefore important to note the sign and magnitude for use to avoid such unnecessary failures. The problem can be so severe in a column to the extent that it leads to a decreased axial load capacity to the given section in which in which the mistake occurs. Under normal circumstances, an increase in the moment of the section is a potential cause of the decrease in axial load capacity hence there is need to adjust the amount of reinforcement by increasing it to a reasonable point. It is therefore important to study moment with respect to the resulting stress since they are major causes of the major problems to a civil engineer.
Guides on the understanding of the flexural forces and how to avoid them
Battaglia, Matteo, Pirrotta and Micale (2017) provided that there are important concepts in the management of beam, for instance, its depth. The depth is specific to a given beam hence there is no standard of measure, however, it is determined by its moment carrying capacity. The significant parts of a building like a slab requires more attention hence there is need to determine their bending moment with regard to their positions in a structure. The bending moment is normally evaluated and used as the basis for determination of the extent of the reinforcement required. This implies the existence of stress can guide a structural engineer on the level and type of adjustment to incorporate to ensure safety and stability of a structure for some considerable period. Understanding the concept is therefore important in establishing an adequate support to a beam which would unnecessarily be liable to destruction after a relatively short time.
Determining the effect of external forces
The voices applied on a beam may turn out to be effective if they overwhelm the beam itself. This depends on the magnitude and direction of the force applied. Besides, it depends on the ability of the beam in question to resist such forces. Stress is a condition which makes a beam liable to destruction when a force acts on it. Studying the stresses can guide on what would eh result of a force on a beam which is under the influence of stress (Nath, 2017).
