Planning and Design of Large Dams
Any dam project is carried out in the following stages: 1. Initial screening is conducted based on river profile and topographic maps. 2. Reconnaissance plan is developed using only already available data. 3. Pre-feasibility plan is developed with a little exploration and additional field data. 4. Feasibility plan is developed withEl Caj贸n Dam Mexico - Design and Construction
El Caj贸n dam, Mexico, has a 188 m high concrete-face rockfill dam. The El Caj贸n Dam is a hydroelectric dam on the R铆o Grande de Santiago in the Mexican state of Nayarit. Construction began in 2003 and was completed in June 2007. It cost US$800 million to build. It is 640 m (2,100 ft) long and is 178 m (584 ft) high.

Seismic Design & Earthquake Resistant Construction
Earthquake resistance is the ability of the structure to withstand earthquakes. These structures perform better during the earthquakes and give sufficient time to its dwellers to evacuate the building, besides saving lives, reducing injuries and lowering the damages of the earthquake. These structures are intended to withstand the largest earthquake of a
Factors Affecting Design of a Barrage
Factors affecting the Design of Barrage are as follows: Estimation of Design Flood Hydraulic Units Width of Barrage Afflux Tail Water Rating Curve Crest Levels Discharges through a Barrage (Free Flow Conditions) Discharge through a Barrage (Submerged Flow Conditions) Fane's Curve Gibson's Curve
Roller Compacted Concrete Mix Design and Properties
The consolidation by a roller does not require special cements; however, when RCC is to be used in mass concrete, the recommendation of selecting cements with lower heat generation. Mineral admixtures are used extensively in RCC mixtures. The use of large amounts of mineral admixtures reduces both the adiabatic temperature rise of concrete and costs, and
Parameters considered in Designing Spillways
The topography, hydrology, hydraulics, geology and economic considerations all have a bearing on these decisions. For a given inflow flood hydro graph, the maximum rise in the reservoir level depends on the discharge characteristics of the spillway crest and its size and can be obtained by flood routing. Trial with different sizes can then help in getting the optimum combination
History, Design and Construction of Taj Mahal
History "A white marble tomb built in 1631-48 in Agra, seat of the Mugal Empire, by Shah Jehan for his wife, Arjuman Banu Begum, the monument sums up many of the formal themes that have played through Islamic architecture. Its refined elegance is a conspicuous contrast both to the Hindu architecture of pre-Islamic India, with its thick walls, corbeled arches, and heavy lintels,
Design of Weir and Conditions for Stability & Maximum stress
In any hydropower projects the diversion structures occupies the key position. Among these diverging structures weir is the most commonly used structure, because of its simple design and operation. Different types of weir can be used as diverging structures some of them are given below: Sharp crested weir Broad crested weir Ogee weir Tyrolean weir weir with lateral intake etcDesign of Water Channel (Canals)
The channel is the same thing that is used for the water carriage purpose, however in case of hydropower projects the channel that takes water from the intake (Diversion Structure) is usually called connecting channel. It's tunnel is to be used in between the intake and power house otherwise called headrace channel, if no tunnel is to be used in between the intake andSteps in Designing a Transfer Floor
Design of reinforced concrete transfer floors, although routinely performed by structural design engineers, is a very challenging task. The transfer floors are commonly used in multi-storey buildings, and they are major structural elements carrying a number of floors. Normally the entire building, 10 to 15 levels, is carried by a transfer slabs. The major problem is the evaluationDesign of Steel Beam - Design Principles and Considerations
The development of a plastic stress distribution over the cross-section can be hindered by two different length effects: A simply supported beam can be subjected to gravity transverse loading. Due to this loading the beam will deflect downward and its upper part will be placed in compression and hence will act as compression member. Beams are generally
Functions of Slab and Design of Slab
A flat piece of concrete, put on the walls or columns of a structure. It serves as a walking surface but may also serve as a load bearing member, as in slab homes. Its necessary to check the slab deflection for all load cases both for short and long term basis. In general, under full service load, Deflection (d) < L/250 or 40 mm whichever is smaller. Check for lateral
