Project Report from the year 2019 in the subject Engineering - Civil Engineering, grade: A, University Kebangsaan Malaysia (Asia Pacific University), language: English, abstract: This group assignment focuses on the design of house decks that can withstand heavy rain during spring and autumn, considering various structural criteria. Each group member is tasked with designing at least two beams with different shapes, evaluating their dimensions, and analyzing their structural integrity under distributed and concentrated forces. The design selection process involves calculating bending moments, determining the second moment of inertia, and assessing maximum bending stress on the beams. The factor of safety is then employed to identify the most suitable material based on tensile strength. The research highlights the significant impact of beam shape on strength, emphasizing the need for material selection based on engineering properties. The outcome underscores the importance of choosing materials carefully to ensure optimal structural performance in house deck designs exposed to heavy rain. The research concludes with a justification for the most suitable beam design among the members, offering valuable insights for engineering applications.
