ature shows the attention which is being devoted to the subject of hernia. It is only within the last few years that the radical cure of hernia has come within the range of practical surgery. In this country, where there is difficulty in obtaining suitable appliances, and where surgical help is not always immediately available, a radical cure becomes of primary importance. In England it will li...

truss is considered as equivalent to a beam with shear flexibility. the web thickness of the equivalent beam is calculated for various truss forms. the basic relations utilized in the analysis of structural systems composed of beams with shear flexibility, by means of the force method and the slope - deflection method, are presented. finally, the tables to be used in the analysis of contineous ...

Using the example of trusses the paper demonstrates the strong influence of a scientific view on structures and structural concepts arising at the beginning of the 19 century in Western Europe. By then structures have been considered as assembled constructs arranged according to utilization and boundary conditions. In most cases, such structures were designed and built based on samples, which h...

This paper presents the optimization of metal-plate-connected plane timber trusses with special emphasis on joint flexibility. The optimization is performed by the non-linear programming approach. Since various truss design parameters such as type of truss configuration, span/depth ratio, number and type of diagonal and vertical members and type of joint connections simultaneously affect each o...
