剪跨比a h _ 0 1的短鋼筋混凝土牛腿，其受力性能接近於懸臂深梁，在建築結構中是支承屋架、屋面梁、托架、托架梁、框架梁、墻梁和吊車梁等的重要構件。 -
The garret, built to be a depository for firewood and the like, was dim and dark : for the window of dormer shape, was in truth a door in the roof, with a little crane over it for the hoisting up of stores from the street : unglazed, anal closing up the middle in two pieces, like any other door of french construction
閣樓原是做儲藏室堆放柴禾之類的東西用的，十分陰暗那老虎窗樣的窗戶其實是房頂的一道門，門上還有一個活動吊鉤，是用來從街而起吊儲藏品的。那門沒有油漆過，是一道雙扇門，跟一般法國式建築一樣，從當中關閉。 -
The paper develops the basic system of state - appraisal method aiming at monolayer steel structure workshop ; according to the influence factor of structural reliability, the paper also establishes the appraisal index and gradation principle to the effect foundation column - system roof covering - system and crane girder - system ; the appraisal method of main index of unit section ' s shortening surface temperature and deformation is especially researched ; the integrated appraisal method of structural reliability of industrial building is set up on the basis
論文針對單層鋼結構廠房，首先建立了狀態評定方法的基本體系：根據結構可靠性的影響因素，進一步建立了作用、地基基礎、柱系統、屋蓋系統、吊車梁系統的評定指標和分級原則；專門研究了構件截面消弱、表面溫度、構件變形等主要指標的評定方法；在此基礎上，建立了廠房結構可靠性的綜合評定方法。 -
Assemble design is very important as a part of bridge crane design. as a visual reality technology applied in design and manufactual field, visual assemble technology has been gained quiet great development. some visual assemble system has been applied in industry. the research in this paper is combining vr and cad technology, to develop a special design system for bridge crane. in the study, we choose a advanced 3 - d cad software - solidworks to modeling the crane, and use an object oriented computer language - visual basic for secondary development of solidworks by its api function and ole interface. in this paper, it will introduce the crane ’ s automatic assembly and collision detection function of design system. the system program is written in visual basic and hanged to solidworks flat roof. so, it seems solidworks runs its own function when we run the program
本文的研究工作將虛擬現實技術與三維cad技術相結合，研究橋式起重機的虛擬自動裝配及裝配中的干涉檢查。在此研究中，作者選用先進的三維cad軟體平臺- solidworks ，進行起重機的建模;並運用面向對象的設計語言- visualbasic ，利用solidworks的api函數和ole介面對其進行二次開發，開發出起重機小車的創新虛擬裝配設計和干涉檢查系統。此設計系統是通過vb編程，在solidworks軟體平臺上外掛系統程序，程序的運行就如同solidworks調用自身功能一樣，來實現設計功能。
