視覚化による積載荷重の説明性に関する研究

摘要

建築基準法施行令第八十五条では設計用積載荷重値は対象建物の実況に応じることとなっているが、実務では同施行令や建築物荷重指針・同解説1）で示されている略算値を慣用的に用いる傾向が強い。しかし、略算値が全ての荷重状況を許容できるとは限らず、過荷重が原因で住宅の2階の床が落ちるといった事故が生じている。%The authors attempt to visually express a lived load of buildings for advance decision making between owners and designers. Therefore, how a visual element perceives this view (area and position of brightness, size, sufficiency level) was determined using a questionnaire that included the model photograph. Methods have been devised to determine whether the visual perception of a live load is possible, and if so, to what extent the view can be perceived. The possibility of making an explanatory tool that expresses the best live load for a target was shown by changing the brightness and the size of the furniture according to the type of visual perception the target had. We made a prototype of the explanatory tool for trial purposes.
