Civil Engineer Tricks

The above images shows the design of school building.It is  a G+ 10 building designed for wind force also.It consists of isolated foundation with beams and columns of size as per specifications.There is a shear wall running throughout of this building.

The above figure shows decorative fencing.This kind of fencing is an unique one and concreting of this kind of fencing is not easy in installation.Nearely 3 stages is followed in concrete.

The above figure shows a plinth beam.Buclkling of this beam occured at the middle of the support.It occured during the vibration of the concrete while concreting is done.The reason for this buckling is improper prop support or inadequate props along the length of this beam.It can be avoided by carefully monitoring the props before laying the concrete.

Answer -Identify the material The name of the above material is safety or warning tape.Usually it is burried under the soil.It is used to identify that some material is underlaid below it.Generally water pipelines,sewerage lines,high voltage cables,gas pipelines are used with such material.This warning tape is at a height of almost 300mm above the pipelines,cable lines etc,.It gives warning to the people while excavating the soil that some pipelins,cables below it.

Identifiy the above material what is the name of this material ?where it is used for?

   Answer  for Identification of the construction material:       The material behind this tree is named as sediment fence.It is made up of geotextile and wooden piles.The white colour cloth shown is the geotextile snd the wooden piles are used to stick the cloths to the required height and length.This kind of sediment fence is laid arouund wherever soil cutting takes place on the hilly regions.The main reason behind using this material is it traps the soil which are blown away by the wind or storm which might enter to the road,pathways or drainages,etc.

Can anyone identify the material behind this tree...what is the purpose of this material?Where it is used?

The name of this plantation is  Chrysopogon zizanioides .local name is vetiver.  This plantation can grow upto a height of 1.5 m.It  is used mainly for purificaton of water.that is to remove the Total dissolved solid(TDS) from water.so many research ere going on this plantation for TDS removel.

Can anyone Identify this plantation?What is the name of this plantation ?were it is used?

What is the error can be identified with this RC beam??

  The above monument is named as brahadeeshwar temple.This monument is constructed by the great RAJA RAJA CHOLA.It is located in southern India,Tamil Nadu.It was constructed before 1000years.So many engineering concepts were hidden with this monument.It is ahollow pyramid in shape with 13 stories.The height of this structure around 220 feet.the weight gopuram of this 80 tonnes.   The intersting fact is how this kind of structure can be built without any help of the enineering equipments before 1000 years.One more fact is there is no rocky mountain around this city.It is properly designed structure with beam, columns,slabs resting on the centre of gravity of each one.No mortar is used for filling the joints.The foundation  for this very shallow.It is not affected by any of the seismic forces  for 1000 years.Still so many engineering tricks are behind this great monument.

Materrial identification-construction materials What id the name of the material ??where it is installed?what would be the purpose of using this materiL?Can anyone identify?   The name of this material is Aluminium foil.It is also named as sisalation.It is used in roofed structures.The main purpose for using this material is to reflect the sun radiation and heat entering in to the buildings.   It is classifed as single side and double sided aluminium foil

Repair of slab-spalling of concrete-Reason The reason for this spalling of concrete are due to corrosion. due to this corrosion the reinforcement undergoes two stage.In the first stage the diameter of the bar gets increased.second stage the diameter of the bar decreased consequently the strength of the bar gets reduced.Due to the expansion of the bar in first stage the spalling of concrete occurs.

Desalinatioin plant-pump house The desalination plant is used to remove the salt content from the salt water.The sea water usually consists highly dissolved salt content namely chloride,sodium etc.due to this salt content it cannot be used for domestic and construction purpose.To convert the sea water to portable one several steps are followed which can be discussed one by one.The above figure shows the pump house.Here the water from the sea is pumped in and subjected to further process.

Spalling of concrete on slabs The above piicture shows the spalling of concrete on the bottom of slabs.What could be the reason behind this?Please comment.

Sedimentation pond-Inlet and Outlet drain The picture shows the inlet and outlet drain for the sedimentation pond through which the collected and drained out of the pond.The inlet and outlet drain are always in downward slope so that the water flows under gravity.so many small crust are made along the pathway of drain.It collect the floating particles like leaves,wood etc.

Sedimentation pond:             The sedimentation pond is Eco-friendly system. It is used were there is cutting of soil ,mountains,hills etc are done.The purpose of this pond is to collect the silt content which will mingle with the main drainage system and cause the pollution.In this picture there is a barrier made up of arrangement of boulders which is covered with Geo-textile. This Geo-textile traps the silt and it is deposited on the bottom of the pond.There is a spillway on the top of the barrier through which the excess water is spilled away.

A response spectrum is simply a plot of the peak or steady-state response (displacement, velocity or acceleration) of a series of oscillators of varying natural frequency , that are forced into motion by the same base vibration or shock . The resulting plot can then be used to pick off the response of any linear system, given its natural frequency of oscillation. One such use is in assessing the peak response of buildings to earthquakes . The science of strong ground motion may use some values from the ground response spectrum (calculated from recordings of surface ground motion from seismographs ) for correlation with seismic damage. If the input used in calculating a response spectrum is steady-state periodic, then the steady-state result is recorded. Damping must be present, or else the response will be infinite. For transient input (such as seismic ground motion), the peak response is reported. Some level of damping is generally assumed, but a value will be obtained even wit...

Spherical sliding isolation systems are another type of base isolation. The building is supported by bearing pads that have a curved surface and low friction. During an earthquake the building is free to slide on the bearings. Since the bearings have a curved surface, the building slides both horizontally and vertically. The forces needed to move the building upwards limits the horizontal or lateral forces which would otherwise cause building deformations. Also by adjusting the radius of the bearings curved surface, this property can be used to design bearings that also lengthen the buildings period of vibration

Lead-rubber bearings are the frequently-used types of base isolation bearings. A lead rubber bearing is made from layers of rubber sandwiched together with layers of steel. In the middle of the solid lead “plug”. On top and bottom, the bearing is fitted with steel plates which are used to attach the bearing to the building and foundation. The bearing is very stiff and strong in the vertical direction, but flexible in the horizontal direction. How it Works To get a basic idea of how base isolation works, first examine the above diagram. This shows an earthquake acting on base isolated building and a conventional, fixed-base, building. As a result of an earthquake, the ground beneath each building begins to move. . Each building responds with movement which tends towards the right. The buildings displacement in the direction opposite the ground motion is actually due to inertia. The inertia forces acting on a building are the most important of all those generated during an earthqu...
