Structural Engineering ppt is the back bone of civil engineering and is one of the most sophisticated branch in civil engineering. Hence, the subject is very vast and advancing over time.

The branch basically deals with analysis and design of structures. The design materials are usually wood, concrete,, PSC and other advanced materials. This branch has always attracted young civil engineers to pursue a careen in. It deals with design of buildings, bridges, dams, ports and other utility structures. You can of civil presentations on structural engineering here. Transportation Engineering ppt Design, Construction and management of roads and highways is a serious business.

From the concept stage onwards there are multiple stages involved like traffic survey, functional planning & design, operation and management of transport facilities. Utmost care is given to safety and efficiency in design to produce a convenient and economical design. It is an interdisciplinary brach by itself and coordinates with multiple branches for working.

A schematic image of three types of cantilever. The top example has a full moment connection (like a horizontal flagpole bolted to the side of a building). The middle example is created by an extension of a simple supported beam (such as the way a is anchored and extends over the edge of a swimming pool).

The bottom example is created by adding a to the beam element, which essentially adds an elastic spring to the end board. C For C Programmers Third Edition Ira Pohl Pdf Free Download. The middle and bottom example may be considered structurally equivalent, depending on the effective stiffness of the spring and beam element A cantilever is a rigid, such as a or a plate, anchored at only one end to a (usually vertical) support from which it is protruding; this could also be a perpendicular connection to a flat vertical surface such as a wall. Cantilevers can also be constructed with. When subjected to a, the cantilever carries the load to the support where it is forced against by a and. Cantilever construction allows for overhanging structures without external bracing, in contrast to constructions supported at both ends with loads applied between the supports, such as a simply supported beam found in a system. Contents • • • • • • • • • • In bridges, towers, and buildings [ ] Cantilevers are widely found in construction, notably in and (see ).

In cantilever bridges the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The in is an example of a cantilever. A cantilever in a traditionally building is called a. In the southern United States a historic barn type is the cantilever barn of. Temporary cantilevers are often used in construction. The partially constructed structure creates a cantilever, but the completed structure does not act as a cantilever. This is very helpful when temporary supports, or, cannot be used to support the structure while it is being built (e.g., over a busy roadway or river, or in a deep valley).

So some (see ) are built from each side as cantilevers until the spans reach each other and are then jacked apart to stress them in compression before final joining. Nearly all are built using cantilevers as this is one of their chief advantages. Many box girder bridges are built, or in short pieces. This type of construction lends itself well to balanced cantilever construction where the bridge is built in both directions from a single support. These structures are highly based on and rotational equilibrium. In an architectural application, 's used cantilevers to project large balconies. The East Stand at Stadium in Leeds was, when completed, the largest cantilever stand in the world holding 17,000 spectators.

The built over the stands at uses a cantilever so that no supports will block views of the field. The old, now demolished had a similar roof over the spectator area.

The largest cantilevered roof in Europe is located at in, the home stadium of Less obvious examples of cantilevers are free-standing (vertical) without, and, which resist being blown over by the wind through cantilever action at their base. The pioneering all-metal monoplane of 1915, the first aircraft to fly with cantilever wings Another use of the cantilever is in design, pioneered by in 1915.

Early aircraft wings typically bore their loads by using two (or more) wings in a configuration braced with and. They were similar to, having been developed by, a railroad bridge engineer. The wings were braced with crossed wires so they would stay parallel, as well as front-to-back to resist twisting, running diagonally between adjacent strut anchorages. The cables and struts generated considerable drag, and there was constant experimentation for ways to eliminate them.

It was also desirable to build a aircraft, as the airflow around one wing negatively affects the other in a biplane's airframe design. Early monoplanes used either (as do some current light aircraft), or cables like the 1909 (as do some modern homebuilt aircraft).

The advantage of using struts or cables is a reduction in weight for a given strength, but with the penalty of additional drag. This reduces maximum speed, and increases fuel consumption.

A British from with cantilever wings endeavored to eliminate virtually all major external bracing members, only a dozen years after the ' initial flights, to decrease airframe drag in flight, with the result being the pioneering all-metal monoplane of late 1915, designed from the start with all-metal cantilever wing panels. About a year after the initial success of the Junkers J 1, of also achieved success with a cantilever-winged built instead with wooden materials, the. The most common current wing design is the cantilever. A single large beam, called the main, runs through the wing, typically nearer the at about 25 percent of the total. In flight, the wings generate, and the wing spars are designed to carry this load through the fuselage to the other wing.

To resist fore and aft movement, the wing will usually be fitted with a second smaller drag-spar nearer the, tied to the main spar with structural elements or a stressed skin. The wing must also resist twisting forces, done either by a ' D' tube structure forming the leading edge, or by the aforementioned linking two spars in some form of box beam or structure. Cantilever wings require a much heavier spar than would otherwise be needed in cable-stayed designs. However, as the size of an aircraft increases, the additional weight penalty decreases. Eventually a line was crossed in the 1920s, and designs increasingly turned to the cantilever design. By the 1940s almost all larger aircraft used the cantilever exclusively, even on smaller surfaces such as the horizontal stabilizer, with the of 1939-41 being one of the last World War II fighters in frontline service to have bracing struts for its stabilizer.

In microelectromechanical systems [ ]. MEMS cantilever in resonance Chemical sensor applications [ ] A can be obtained by coating a recognition receptor layer over the upper side of a microcantilever beam.

A typical application is the immunosensor based on an layer that interacts selectively with a particular and reports about its content in a specimen. In the static mode of operation, the sensor response is represented by the beam bending with respect to a reference microcantilever. Alternatively, microcantilever sensors can be operated in the dynamic mode. In this case, the beam vibrates at its resonance frequency and a variation in this parameter indicates the concentration of the. In storage applications [ ] Warehouse storage [ ] A cantilever rack is a type of storage system consisting of the vertical column, the base, the arms, and the horizontal and/or cross bracing. These components are fabricated from both roll formed and structural steel.

The horizontal and/or cross bracing are used to connect two or more columns together. They are commonly found in, woodworking shops, and plumbing supply warehouses. Portable storage [ ] A folding cantilever tray is a type of stacked shelf that can be unfolded to allow convenient access to items on multiple tiers simultaneously. The shelves can be collapsed when not in use for more compact storage. Because of these properties folding cantilever trays are often used in and.
