Civil Engineering

Civil engineering is a professional engineering discipline that deals with the design, construction and maintenance of the physical and naturally built environment. This includes works like roads, bridges, canals, dams, and buildings. Civil engineering is one of the oldest engineering disciplines. Civil engineering takes place on all levels of society including the public and private sectors.

The history of civil engineering link advances of physics and mathematics throughout history. The applications of physical and scientific principles are understood. Civil engineering has a wide range of professions including several separate specialized sub-disciplines. The history of these sub disciplines are linked to knowledge of structures, materials science, geography, geology, soils, hydrology, environment and mechanics.

Civil engineers have an academic degree with a major in civil engineering. The length of this degree is typically three to five years. In the majority of countries, a Bachelor’s degree in engineering represents the first step towards a professional certification and the degree itself is certified by a processional body. After completion of a certified degree program, an engineer must satisfy a range of requirements before being certified.

Fire Dynamics: Energy Release and Ceiling Ventilation

An atrium has a floor area of 30 m by 20 m and is 20 m high. The ceiling ventilation is designed for a fuel area of 30 m2 with an energy release rate of 0.5 MW/m2. The inlet openings are very large. An effective heat conduction coefficient can be assumed to be 20 W/m2°C. (a) Calculate the area of ceiling vents required for e

Drawing Tender Package

One of engineering company providing drawings at the end of the Month. I have emailed set of questions to engineering company to include every thing in the drawings tender package. I just do not want to miss any question.....If I did not include any questions which might you come across let me know. At this point, if any one

Determine the most economical and safe design

An axial load P is supported by a short W8 X 40 column of a cross-sectional area A = 11.7 in2 (inches squared) and is distributed to a concrete foundation by a square plate as shown (in the attachment) Knowing that the average normal stress in the column must not exceed 35 ksi and that the bearing stress on the concrete foundati

Determine the concrete footing of an axial load

A 20-kips axial load is applied to a short wooden post which is supported by a concrete footing resting on undisturbed soil as shown. Determine the size "b" of the concrete footing if the average bearing stress on the soil is not to exceed 30 psi. a. b = 25.8 in. b. b = 22.4 in. c. b = 18.3 in. d. b = 15.8 in.

Penalty Cost Calculation

Having problems calculating the penalty cost. Please see attached. The U.S. Army Corps of Engineers issues purchase instructions informing potential suppliers that roadway graders will be evaluated using the following life cycle cost model: LCC = unit operating cost, dollars = (un

Determining Cost Estimating Function

A product plant is being considered for a new booming market. Total fixed cost for design, land, and plant construction is $105. The variable cost of producing product is a function C (n) = 100n - 3 x 10-3 n2 + 10-7 n3 where n = number of product produced. (a) Determine the total cost function C (T). (Hint: It includes the

Deflection of a Beam

If a beam of lenght L is fixed at the ends and loaded in the centre of the beam by a point load of F newtons the deflection at a distance x from one end is given by : y= (F/ 48Ei)(3L^2x-4x^3) Find the position and the value of the maximum deflection of the beam if; L = 10 m Ei= 300x10^6 Nm^2 F= 100kN

Bending moment in a timber beam

Base isolation technique

Base isolation technique has become the method of choice for structural design of buildings and bridges located in highly seismic areas in recent years. Please provide of an overview of this approach. Also, discuss the application of rolling type bearings for equipment isolation.

Determine Maximum Allowable Load

A rigid steel plate is supported by three posts of high-strength concrete each having an effective cross-sectional area A=40,000 mm^2 and Length L=2 m (see attachment). Before the load P is applied, the middle post is shorter than the others by an amount s=1.0 mm. Determine the maximum allowable load Pallow if the allowable com
