From the first truss bridge, engineers experimented with different forms of truss bridges trying to find better shape and the one that will suit them for the particular problems. Because of that we have today many forms of truss bridges. Truss bridge can have deck (roadbed) on top (deck truss), in the middle (through truss), or at the bottom of the truss. If the sides of the truss extend above the roadbed but are not connected, it is called a pony truss or half-through truss. The common concept design used in a truss bridges are Basic Warren Truss Bridge Basic Pratt Truss Bridge , Howe Truss Bridge & K-Truss Bridge .
The same argument applies if the fluid is stationary and the body is moving: a force is needed to propel an aircraft through the atmosphere. The force needed depends upon many factors including the coefficient of drag, C¬D, and the cross sectional area of the body presented to the flow, A: ΔP/(1/2 ρu^2
As the chain link is symmetric in many ways, we used only a part of the chain link for our analysis. The cut portion of the chain link is as shown in the figure. We have fixed the end of the straight (fixed support) portion and applied the load to the inner region of the circular portion as shown in the
A truss bridge also has a truss, a structure of connected elements, on top of it. The truss’s elements are mostly triangles. This is supposed to spread out the weight. Rather than having a narrow space where all of the weight is, it makes a wider area where all of the weight can be spread out. This puts less stress on the beam.
In other words, we can say that when the centers of all the masses (disturbing as well as balancing masses) lie on the axis of rotation i.e. when the line of action of all the centrifugal forces is the same. Dynamic Balancing (Complete Balancing): When the net couple acting on the shaft is also made equal to zero along with the net dynamic forces to be zero, this is what we call as dynamic Balancing i.e. when the sum of the moments at any point in the plane is equal to zero. Basically during the static balancing, we introduce balancing mass (or masses) which generate equal but opposite centrifugal force in order to balance or cancel the effect of already existed centrifugal force.
This subject interests me because it requires verity physical and hard work. I see my self more physical person than sitting to a dick, I chose this course because I’m interested creating and building new structure and design. Structural engineering is mostly concerned about the design and building structure which include planning, design, construction, inspection, monitoring, maintenance, reintegration and demolition of permanent and temporary structures, as well as structural systems and their components. Structural engineering is also concerned about the technical, economic, environmental, visual and social aspects of structures. Structural engineering is a creative passion that enables you to create major contribution infrastructure, as well as recreational development.
In the conventional design of practice check for the beam column joint is not critical, but for the seismic point of view it is necessary to check the joint. In the study beam –column joints are taken as rigid joints. The basic need of the joint design improves the shear strength of the joint. Beam column joint are of three types, interior joint, exterior and corner
