關於房屋排架在風及其他側力或偏心荷載下之應力分析,英美結構書籍多令各個排架之側移各自獨立,不由其鄰近之排架分担,因此排架所需之截面較大,頗不經濟。蘇聯的先進方法係於每排柱頂,各置縱向平面聯結系一道,將所有排架於縱向聯成一體,如是則任一排架在荷載下所發生之側移,將因聯結系的作用,由若干鄰近的排架分担而相當減少。本文的目的,除於理論上證明排架侧移在縱向之此項分佈作用外,並列舉排架在集中側力(如吊車的水平制動力)及均佈側力(如風荷載)作用下,其側移縱向分佈的計算方法,以供設計工程師之參考或採用。
With regard to the stress analysis of the house pylon under the wind and other lateral forces or eccentric loads, the Anglo-American structural books often make the sides of the individual trusses move independently and are not shared by adjacent trusses. Therefore, the framing requires a relatively large section. Not economical. The Soviet Union’s advanced method is based on the top of each row of columns, each of which is connected with a longitudinal plane and connects all the rows of racks in the vertical direction. If any of the rows of racks moves sideways under load, it will be affected by the coupling system. It is divided by a number of adjacent bays and is rather reduced. The purpose of this paper is to theoretically demonstrate the effect of the lateral displacement of the girder in the longitudinal direction, and lists the girders under the influence of concentrated lateral forces (such as the horizontal braking force of the crane) and uniform lateral forces (such as wind load). The method of calculating the longitudinal distribution of lateral shifts is for reference or adoption by the design engineer.
