著者在本文裹提出了確定结構物安全度的新方法——半或然率法。这个方法以統計学和或然率理論为基礎。它採用了一系列考慮結構具体受力条件的係數,与允許应力法不同。它可以藉助其他在統計学力面研究較好的事故或然率与建築事故或然率相比較的方法,从而使我们有可能將它应用於因缺乏某些統訓資料而不能应用極限狀态法的國家。用这个方法不須要確定一个最低的屈服極限,所以有可能在相应的情况下提高允許应力。因此,作为一个结構物安全度科学方面的新方向,这个方法是值得土木工程師的注意的。

利用竹材做建筑物代替钢材及木材,在今天祖國社会主義建設有著重大的意義。竹材的性能在許多方面有其优点的,但是也還有许多缺点。(如中空端头、收縮开裂、易腐及生虫等。)假如不能克服其缺点,則其优点是不能很好利用的。本文针对竹材的中空端头、收縮开裂等缺点進行改造加工。通过試驗及研究證明:利用酪素—水泥膠把廢木料圆(?)或木板膠入竹桿或竹片端头或有節点处,这样竹桿件所制造出的各种型式竹結構是完全类似木結構的,可以說由構造上解决了結合困难,並且有了安全的保証。本文首先介紹了此型竹結結構的各种图式及合适跨度(图1),然后介紹竹桿的基本改選方法(圖3)及各式節点的構造方案(圖4),以及其簡單計算的举例(§2-7);最后简要介紹有关改造加工的施工工藝(§3)。本文認为若用作过防腐及防虫处理的竹材,再通过以上改造所制造的竹結構会能够比較安全的長期使用。(半永久性的而不再是臨时性的建筑。)

This paper presents the method of caleulation of reinforced concrete structures by using the mathmatical method of statistical analysis.The axiliary factor of safety k or its reversal k' is calculated by using the mathmatical method of statisti- cal analysis,cosidering the combined effect of variation in strength of materials, area of section and applied loading.In the final formula are introduced k or k' and the coefficients of working conditions m and ma,considering the working characteristics of structures and materials themselms. By introducing the original form of axiliary factor R=r-q,the general formu-las for calculation of k and k'are given as follows: The working formulas for calculation of structures are put in the final forms: Lastly the problems that still have to be further studied are discussed.
