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.

In this paper,the Authors analysed the loads on the windlass as well as the steering gear of Yangtze River boats. The load acting on a windlass may appear in one of the following three eases: 1.The load for hoisting anchor; 2.The load as the anchor dropped to moor the boat; 3.The load for breaking the chain as the boat in accident. The load in third ease is maximum,moderate in first case,and minimum in second case.The third case had happened before among the Yangtze River boats,hence,it should be considered....

In this paper,the Authors analysed the loads on the windlass as well as the steering gear of Yangtze River boats. The load acting on a windlass may appear in one of the following three eases: 1.The load for hoisting anchor; 2.The load as the anchor dropped to moor the boat; 3.The load for breaking the chain as the boat in accident. The load in third ease is maximum,moderate in first case,and minimum in second case.The third case had happened before among the Yangtze River boats,hence,it should be considered. However,the dimensions of machine elements of a windlass may be too clumsy,if they are determined according to the third case.The Authors propose that they may be determined by following method: to check the fatigue streugth by the maximum load at the time of hoisting the anchor;and to keep the stress of material just below the yield point at the time of breaking the ehain. Based upon some investigations,it is easy to find out that the usual service rudder angles of Yangtze River boats are all within 20°.By applying statistical method to various forms of rudder; the ratio of the maximum torque of rudder angle below 20°to the maximum torque of all rudder angles is mostly less than 50%,and only few cases are more than 50%. From the above analysis,the Authors propose that the maximum torque may be treated as a peak load,and half of the peak value is assumed as a maximum load of usual service in calculating the strength of machine elements. With above point of view,a method for calculating the strength of principal machine elements of windlass and steering gear is briefly described,and some practical examples are given. The power of motor may be determined by the torque and speed of rotation.The heavy load acting on these kind of machines is always in a very short period.In order to utilize full power of motor,the Authors propose to multiply the maximum torque of motor by a coefficient of safety to meet the corresponding maximum torque of windlass or steering gear.This coefficient of steering gear and windlass may be taken as 0.8 and 0.7 respectively.The motor is mostly operating in a low load condition,hence the influence of decreasing speed in over load may not be considered.

本文对长江船舶起锚机和舵机在工作中所承受的负荷进行了分析。起锚机的负荷可分为三种情况:1.起锚时的负荷;2.抛锚后,锚已入土将船固定时的负荷;3.当船遇险时,将锚链拉断所承受的负荷。第3种负荷最大,第1种次之,第2种最小。第3种情况在长江曾经遇到,不能不考虑。但是,若按此确定机件的尺度就会感到过于笨重。作者建议按下述原则来确定机件的尺度:按起锚时的最大负荷来核算机件的疲劳强度;当承受锚链拉断负荷时,其应力不能超过材料的屈伏极限。根据调查,发现长江船舶常用转舵角均在20°以内。统计了各种舵型在20°以内的最大转矩与在全部转角范围内的最大转矩之比值。此值绝大多数均小于50%,仅有少数舵型超过50%。根据这些情况,作者建议以最大转矩作为尖峯负荷处理,而以它的一半作为经常使用的最大转矩来计算机件的强度。应用上述观点,对起锚机和舵机常用的几个主要零件的强度计算方法作了简单的叙述;并给出一些具体例子。电动机的功率可以由转矩和转速来决定。这类机械所承受的重负荷都是短期的。为了充分利用电动机的潜在能力,建议以电动机的最大转矩乘以裕度系数来适应起锚机和舵机所需要的最大转矩。舵机裕度系数取为0.8;起锚机的取为0.7。电动机在低...
