in the longitudinal direction of the structural element. This force prevents the cracks from developing by eliminating or considerably reducing the tensile stresses at the critical midspan and support sections at service load‚ thereby raising the bending‚ shear‚ and torsional capacities of the sections. The sections are then able to behave elastically‚ and almost the full capacity of the concrete in compression can be efficiently utilized across the entire depth of the concrete sections when all

What is Stress Analysis? The aim of stress analysis is to take the geometry of a component or structure and the externally applied “loads” and determine the state of stress in the material. Subjects that encompass stress analysis include “strength of materials”‚ “solid mechanics”‚ mechanics

Africa and Asia‚ building bridges and roads of very high quality. 2- Different types of bridge designs (include diagrams and labels) The beam bridge... consists of a horizontal beam supported at each end by piers. The weight of the beam pushes straight down on the piers. The farther apart its piers‚ the weaker the beam becomes. This is why beam bridges rarely span more than 250 feet. The truss bridge... consists of an assembly of triangles. Truss bridges are commonly made

stretching occurs at 2960 cm−1 . By comparison‚ methylene groups show asymmetric stretching at 2930 cm−1 and symmetric stretching at 2850 cm−1 . C–H bending gives rise to bands in the region below 1500 cm−1 . Methyl groups produce two bending bands‚ i.e. a symmetrical band at 1380 cm−1 and an asymmetrical band at 1475 cm−1 . Methylene groups give rise to four bending vibrations: scissoring (1465 cm−1 )‚ rocking (720 cm−1 )‚ wagging (1305 cm−1 ) and twisting (1300 cm−1 ). The intensity of the methylene CH2

which are known as the cruck blades‚ these are often cut from the same tree by cutting right down the middle of the trunk‚ this means that whatever the shape (twist/bend) the pair will be identical. A collar/tie beam would sometimes be added in order to brace the frame and to stop it from bending/twisting. The cruck frame is the key element in cruck construction as the frame carries the whole load directly to the ground. “This type of construction continued until the early part of the 18th Century in
