プレカットを用いた木造軸組住宅（四号建築物）に関する研究: 樣規定から見た四号建築物の実態

摘要

本研究では仕樣規定に着目して、仕様規定から見た建物の安全性を調査した。既往研究においては、柱•壁直下率と定性評項目の観きから、架構を意識せずに設計している設計者が少なくない可能性を指摘したが、本研究で対象とした物件について壁量と直下率の関係を調査したところ、明確な相関は見られなかつた。%"The fourth building, special case system" is applied to a building in case of application for building confirmation number four, and it's possible to omit a part drawing and specification. While a precut method of construction is the mainstream, it's becoming general that an engine frame designer makes a framing plan. But an engine frame designer can't feed back to a design designer because application for building confirmation is being performed first even if there is a problem with a scheme design, and there is a problem that a design can't be reconsidered. So I have for my object to grasp the current state of the building number four based on specification code in present Building Standards Law by this research.
