Slope deflection method - Structure Analysis for Civil engineering design

-
Image
 Slope Deflection Method - To analysis of Structures Slope Deflection Method is useful to analyse indeterminate structures. Intdeterminate strutures like continuous beams and plane frames. The unknowns in slope deflection method are degree of freedom i.e. slope and deflection. Combinedly these slope and deflections are known as displacements. Thus slope-deflection method is a displacement method. It is classical method on whick moment distribution method, kani's method and stiffness matrix method are based. Slope Deflection Method - force method or displacement method  It is Displacement method.  Assumptions in Slope Deflection Method - Structure analysis Analysis of a beam and frame means determination of moment and shear force throughout the length of the member i.e. determination of BMD and SFD for the member. BMD and SFD for a member of structure can be drawn if we know the internal end moments of a member Thus, in slope deflection method we establish a relationship b...

 Burj Khalifa - Every Civil Engineers dream Burj Khalifa - Civil Engineers Dream Project Introduction:- Being the tallest building in the world and its beauty attracts anyone in the world.  The edifice is located in Dubai, United Arab Emirates.  With a total height of 829.8 m, the Burj Khalifa has been the tallest structure in the world since 2010.  The building was built within a period of 6 years.  The construction began on 6 January 2004 and ended in the year 2010.  The building was earlier known as Burj Dubai but was renamed in honor of the ruler of Abu Dhabi and the president of the UAE, Khalifa Bin Zayed Al Nahyan.  Burj Khalifa Structure                     The world’s tallest building, Burj Khalifa took 6 years for its construction and was inaugurated on 4 th January 2010. The structure is 828m tall and the whole system is a reinforced concrete tower structure. This was the fi...

Top 10 Most Beautiful Civil Engineering Structures in the World 10. Lake Pontchartrain Causeway 9. Burj Khalifa 8. English Channel Tunnel 7. Golden Gate Bridge  6. Hoover Dam 5. Itaipu Dam 4. Brooklyn Bridge  3. The Colosseum 2. Great Wall of China 1. Great Pyramid of Giza  10. Lake Pontchartrain Causeway   Lake Pontchartrain Causeway The Lake Pontchartrain Causeway in Louisiana (U.S) spans the entirety of Lake Pontchartrain and is 23.83 miles (38.35km) in length. Despite it being opened decades ago in 1959, it is still the longest continuous stretch of bridge over water in the world. The causeway is supported by 9,500 pilings and is so stable that it has suffered a minute amount of damage from major hurricanes and storms when compared to any other causeway worldwide.

Basic Definitions and Simple Tests on Soil Mechanics

Basic Definitions and Simple Tests on Soil Mechanics Introduction This page discuss some of the basic definitions and simple tests used throughout the subject. The phase diagram is a simple, diagrammatic representation of a real soil. The phase diagram is also known as block diagram. A soil mass consists of solid particles, water and air, which are segregated and placed separately, known as three-phase system. A three-phase system becomes a two-phase system when the soil is absolutely dry (solids + air) or when the soil is fully saturated (solids + water). In phase diagram, volumes are represented on the left side, whereas weights are represented on the right side. Volumetric Relationships In total, there are fi ve volumetric relationships. These are as follows: 1. Void ratio (e): It is defi ned as the ratio of volume of voids to volume of solids. Range: e > 0 e = Vv/Vs For some soils, it may have a value even greater than unity. The void ratio of coarse grained soils...

Soil Structure and Clay Mineralogy

Soil Structure and Clay Mineralogy Soil Structure Geometric arrangement of soil particles with respect to one another is known as soil structure. Depending upon the particle size and mode of formation, the following types are found. Single Grained Structure Found in coarse grained soils, like gravel, sand. The major cause for formation is gravitational force. Here the surface forces are negligible. Under the influence of gravitational forces, the grains will assume a particle to particle contact referred to as single grained structure. Single grained structure may be loose or dense as shown below. (a) Loosest state (b) Densest state Honey-comb Structure It is possible for fine sands or silts. Both gravitational force and surface force are responsible. Such a structure can support loads, only under static conditions. Under vibrations and shocks, the structure collapses and large deformations take place. Flocculated Structure This structure occurs in clays. Clay particles h...

Qualities of Good Timber - Building Material - Civil Engineering

-
Qualities of Good Timber Following are the characteristics or qualities of a good timber: 1. Appearance quality of Good Timber:  A freshly cut surface of timber should exhibit hard and shining appearance. 2. Colour quality of Good Timber  :  The colour of timber should preferably be dark. The light colour usually indicates timber with low strength. 3. Defects   quality of Good Timber :  A good timber should be free from serious defects, e.g., dead knots, fl aws, shakes, etc. 4. Durability   quality of Good Timber : A good timber should be durable. It should be capable of resisting the actions of fungi insects, chemicals, physical agencies and mechanical agencies. 5. Elasticity   quality of Good Timber :  This is the property by which timber returns to its original shape when load causing its deformation is removed. This is a sought after property of timber when it is used for making bow, carriage shafts, sport goods, etc. 6. Fibres   quality ...

Natural Seasoning and Artificial Seasoning of Timber

-
Differences between Natural Seasoning and Artificial Seasoning Natural Seasoning  It is difficult to reduce the moisture content below 15–18% It is simple and economical. It is more liable to attack of insects and fungi. It requires more space for stacking. It is a slow process. It gives stronger timber. Artificial Seasoning The moisture content can be reduced to any desired level. It gives weaker timber. It is a quick process. It requires less space for stacking. It is less liable to attack of fungi. It is expensive and highly technical.
