Truss derives from the Old French word trousse, from around 1200, which means "collection of things bound together". The term truss has often been used to describe any assembly of members such as a cruck frame.
The development of railroads in the 1820s has a particular significance for structural engineers.
Railroads created an urgent need for bridges able to carry heavy moving loads and for new building

Next to rectangular and circular columns, L-shaped columns may be the most frequently encountered reinforced concrete columns, since they can be used as a corner column in framed structures. The behaviour of irregular shaped reinforced concrete columns has been a constant concern for a structural engineer, to design a safe and economic structure in modern buildings and bridge piers. L-shaped reinforced concrete column subjected to biaxial bending and axial compression is a common design problem. Axial load capacity and Moment capacity of rectangular and L-shaped reinforced concrete columns have been done in this work.

Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
1. 6. BENDING
In the preceding chapters the behavior of slender members subjected to axial loading and to torsional loading was discussed. In this chapter we will analyze the stresses in, and the deflection of, beams subjected to bending. Bending is a major concept used in the design of many machine and structural component such as beams and girders. Members that are slender and support loadings that are applied perpendicular to their longitudinal axis are called beams. In general, beams are long, straight bars having a constant cross-sectional area. Often they are classified as to how they are supported.
For example, a simply supported beam is a pinned at one end and roller-supported at the other. A cantilevered beam is fixed at one end and free at the other and an overhanging beam has one or both of its ends freely extended over the supports. Certainly beams may be considered among the most important of all structural elements. Examples include members used to support the floor of a building, the deck of a bridge, or the wing of an aircraft. Also, the axle of an automobile, the boom of a crane, even many of the bones of the body act as beams.

Because of the applied loadings, beams develop an internal shear force and bending moment that, in general, vary from point to point along the axis of the beam. To design a beam it will first be necessary to determine the maximum shear and moment in the beam. One way to do this is to express V and M as functions of the arbitrary position x along the beam’s axis. These shear and moment functions can then be plotted and represented by graphs called shear and moment diagrams. The maximum values of V and M can then be obtained from these graphs. Since the shear and moment diagrams provide detailed information about the variation of the shear and moment along the beam’s axis, they are often used by engineers to decide where to place reinforcement materials within the beam or how to proportion the size of the beam at various points along its length.
Beam Sign Convention. Before presenting a method for determining the shear and moment as functions of x and later plotting these functions, it is necessary to establish a sign convention so as to define “positive” and “negative” internal shear force and bending moment. The positive directions require the distributed load to act downward on the beam; the internal shear force to cause a clockwise rotation of the beam segment on which it acts; and the internal moment to cause compression in the top fibers of the segment, or to bend the segment so that it holds water.

6. 6
The shear diagram can be constructed by realizing that each point along the beam the slope of the shear diagram equals the negative intensity of the distributed loading at the point. In a similar manner, the moment diagram can be constructed using data from shear diagram, since the slope of the moment diagram at each point along the beam is equal to the shear at the point. If the shear is equal to zero, then dM/dx=0, and therefore a point of zero shear corresponds to a point of maximum (or possibly minimum) moment.
6.2 GRAPHICAL METHOD FOR CONSTRUCTING SHEAR AND MOMENT DIAGRAMS
Area under the distributed loading curve between A and B is equal to the change in shear between these points. Or stated another way, if the area under the loading curve is positive, due to a positive w, then the change in shear will be negative. Similarly the area under the shear diagram within the region from A to B is equal to the change in moments between A and B.
*If Mo is applied counterclockwise, M is negative so the moment diagram will jump downward.likewise, when Mo acts clockwise, the jump will be upward.
