White and Yellow Marking on Road


Roads are most used transport system worldwide. While travelling through highways or road we see white and yellow markings on roads. few of them are broken and few are Solid continuous. these all markings having some specific objective and meaning as per traffic rules. these are as


1) Solid White Line 



Solid White Line

  • It Means do not change the lane. stay in the your lane.
  • Generally it is used for one way traffic.  






2) Broken White Line 

  • It means you can change your lane if it is safe.

Broken white Line 


3) Solid Yellow Line

  • Mostly used for Two way traffic.  
  • It means that stay in the lane.
  • You may overtake the other vehicles but without crossing the yellow line. No passing is allowed.

Solid Yellow Line


4) Broken Yellow Line 

  • It means you can change the lane on two way traffic roads when it is safe.

Broken Yellow Line


5) Doubled Yellow Line

  • No any passing and overtake is allowed. 

Double Yellow Line

5) One Solid and One Broken Yellow Line 


  • If you are driving through broken yellow line then you can allowed to overtake other vehicle.
  • But if you are driving through either side line then you are not allowed to overtake.

Diffrence Between Flexibility Matrix And Stiffness Matrix

FLEXIBILITY METHOD STIFFNESS MATRIX METHOD This Method is also referred as force or comp ability method. This Method is also called as Displacement method. Primary Unknowns are redundant Forces. Primary Unknowns are Joint displacement. Primary Unknowns can find out by structures comp ability equation. Primary Unknowns are finding out by Solving Structures equation of equilibrium. Flexibility Method deals with Structural Static indeterminacy of structure. Stiffness Method deals with kinematic indeterminacy of structure. In Flexibility Method Primary Unknown forces are like Bending Moment, Shear Force, Axial Force etc. In Stiffness Method Primary Unknowns are Vertical- Horizontal Displacement and Rotation at joint. As Name implies this method is Flexible to choose Unknowns. Stiffness Method Has No such Choice. Bending Moment and Shear Force values of result analys

Pile Cap Design Example as Per Indian Code

Image
Here is a Pile cap design example is solved according to Indian code with step wise procedure. Problem Design pilecap foundation with the given data:  Load Fy = 800 KN, fc = 25 MPa, fy = 415 MPa, Column Dimension = 250 mm x 250 mm. Pedestal ht= 500 mm Pile Data- Dia of pile= 400 mm. Vertical capacity = 250 KN, Horizontal capacity = 100 KN Uplift capacity = 80 KN Solution depth of pilecap= 1.5xpiledia,  D = 600 mm Take D=650 mm c/c pile diatance = 3xpile dia =1200 mm.  Edge diatance = 350 mm Assuming 4 pile combination Pilecap dimension is 1900 mm x1900 mm x 650 mm Weight of footing = 1.9 x1.9 x 0.65 x 25 KN = 58.66 KN Weight of pedestal = 0.25 x 0.25 x 0.5 x 25 KN = 0.78 KN Therefore, total load on the pilecap = (800+58.66 +0.78) KN = 859.44 KN So Pile reaction = 859.44 /4= 214.86 < 250KN Hence OK As there is no lateral load , moment or uplift force, so each pile is sa

Earthquake or Seismic analysis

Image
Seismic analysis is done to determine the seismic forces in the structure.it is based upon analysis applied whether it behaves in elastic state or inelastic state. the analysis is mainly divided in two parts as static analysis and dynamic analysis. Static Analysis - In this method equal magnitude of excitation forces acting over equal time interval. the static analysis is generally used to access the capacity of structural system in terms of deformation and actions. The static analysis may be viewed as a special case of dynamic analysis when damping and inertia effect is zero or almost negligible. it is further divided in two types as linear static analysis and non linear static analysis. Linear static analysis - In this analysis structure behave as elastic corresponding to static types of excitation force and can be used to regular structure having limited height. In elastic analysis, stiffness characteristics of structure is assumed to be constant during whole duration of
