The difference between the beam-coupling gain coefficient Γ and the absorption coefficient α increases at 647 nm from 217 to 361 cm-1 with the increasing strength of a constant electric field E0 applied to the layer from 16 to 123 V/μm.

A method of deflection-proportioning and slope-estimating for computing the wind stresses in multi-storied building frames is presented in this paper. No matter whether the building frame is regular or irregular, this method affords a simple solution with accurate result.

本文舉一位移比率角變估計法,以之分析多層屋架之風應力,該項屋架,不論規則與否,均可利用本法,其所採步驟,既十分簡單,其所得結果,又相當精確。本法首先利用角變位移法,考慮屋架之相對形變,亦即估計屋架各層之相對位移,以及屋架各結點之相對角變。然後利用撓矩分配法,求得柱二端之相對撓矩,尋求該項相對撓矩之時,可以利用第一步之結果,亦即估計柱二端之相對定端撓矩,以及結點四圍之相對傳遞撓矩,先傳遞而後分配之。最後利用疊加原理,觀察屋架各層之相對平向剪力,與共實在平向剪力,成何等之比率。如將第二步之結果,乘以該項比率,則所得之撓矩應為正確之值。

本文目的主要是介紹蘇聯學者在彈性地基上基礎方面的新理論和實用的計算方法,在過去,人們一直採用文克爾(Winkler)在1867年提出的假定,即:地基在某點的壓力是和該點的沉陷有關,並和該點的沉陷成正比,雖然早經認識到這個假定和絕大部分實際情况之間的距離很大,但是一直被因循延用,這確是不能令人滿意的现象,蘇聯學者們提出的新理論,是認為在這個問題的範圍內,土壤是可以應用彈性理論的公式來處理的材料,而將地基看作是一個半無限彈性體,根據土壤力學的理論和實際,這樣的處理是可以滿意地反映實際情况的。新的理論在數學處理上比較困難,本文首先介紹日莫契金教授所提出的計算方法,這在蘇聯是最被廣泛應用的,然後介紹利文在1951午提出的改進力法,由於新理論需要的計算工作十分困難冗長,筆者在上述這些方法的同一原理下,提供了一些十分簡單的計算方法和公式,它們在某一定範圍內有很好的精確度,可供初步設計之用。

Single storied industrial buildings composed of steel trusses and reinforced-concrete columns are very common. As the upper joints are hinged, the stresses in the columns are not influenced by the elastic properties of the trusses; while the upper joints are rigid, methods of analysis are usually based on the assumption that the moment of inertia of a steel truss may be taken as equivalent to that of a beam. In this paper, the author making use of the principle of least work reviews the equations for calculating...

Single storied industrial buildings composed of steel trusses and reinforced-concrete columns are very common. As the upper joints are hinged, the stresses in the columns are not influenced by the elastic properties of the trusses; while the upper joints are rigid, methods of analysis are usually based on the assumption that the moment of inertia of a steel truss may be taken as equivalent to that of a beam. In this paper, the author making use of the principle of least work reviews the equations for calculating the angle-changes at the ends of a truss, and then illustrates their applications with two practical examples: one with flat roof and the other with gabled-roof. They are solved respectively by the method of slopedeflection for the cases of no-sidesway, sidesway-correction and sidesway included by solving the elastic equations of unit deformation. The results are compared with those obtained with usual assumptions.

單層廠房採用鋼架砼柱之混合結構,極為普遍,上端鉸結時柱之應力並不受桁架彈性常數之影響,上端剛結時之分析方法,對於鋼架之截面慣矩每予假定,並代之以假想變,本文作者用最小功能定律以求計算桁架兩端角變常數之公式;再取二實例:一平頂屋架,一脊式屋架,用角變位移法分就無側欹、侧欹校正及單位變位彈性方程解三步驟解出共結果,與一般假定方法所得相互比較。
