摘要
自19世纪以来,工业革命促发了更复杂的建筑工程,结构设计和计算就不再是建筑师的工作内容,从此建筑师仅凭有限的结构类型做设计,限制了方案生成时思维的连贯性、灵活性和创新性。为打破结构类型的禁锢,更深入理解结构类型间的关系,从简支梁的截面作用假想模型出发,将简支梁内力简化为弯矩正应力,以增加梁跨度与结构自重的比值为目标,通过数理论证、物理实验、软件模拟和案例分析等研究方法,定性分析应力、荷载、梁高和梁宽的结构性能化推演过程。研究揭示了演化规律背后的逻辑驱动思维方式,以及数字化技术对材料更加高效配置的积极作用。
Since the 19th century,the Industrial Revolution promoted more complicated architectural engineering,and structural design and calculation were no longer the responsibilities of architects.Since then,architects have relied on a limited number of structural types,which has restricted the coherence,flexibility and innovation of their design thinking.To break free from the constraints of these structural types and gain a deeper understanding of the relationships between them,this study starts with the hypothetical model of section forces of a simply supported beam.It simplifies the internal forces of the beam to the normal stress of the bending moment.Aiming to increase the ratio of the beam span to the structural self-weight,the study employs research methods such as quantitative reasoning,physical experiments,software simulations and case studies.It qualitatively analyzes the structural performance-based deduction processes of stress,load,beam height,and beam width.Ultimately,it reveals the logic-driven thinking behind the evolution patterns and the positive role of digital technology in more efficiently allocating materials.
