Match the conditions under which the given type of footing is used: 

The height of a retaining wall is 5.5 m. It is to be designed as 

A shear key is provided in a retaining wall to avoid 

The imposed floor load acting on staircase for residential and educational buildings is to be considered as

The extreme stress at the top and bottom edges of a prestressed beam when tendons are placed along the longitudinal axis of the beam are

A simply supported rectangular prestressed concrete beam is subjected to uniformly distributed live load over its entire span, such that the resulting stress at the midspan at bottom fiber is zero. The eccentricity at that section is d6 below the C.G., where d is the depth of the beam. Location of the thrust line at that section is

A 4.8 m long post-tensioned prestressed concrete beam is prestressed by a parabolic cable with eccentricity of 15 mm above C.G. at both supports and 45 mm below C.G. at the midspan. The beam is tensioned from one end. In the estimation of maximum loss due to friction, what should be the cumulative angle turned by the parabolic profile ?

In a pre-tensioned prestressed concrete cross-section,

Statement 1:
The stress in wires is assumed to be zero at the end supports and increases to its final maximum value over its transmission length.

Statement 2:

The bond stress between concrete and prestressed wires is maximum near the end supports and decreases to nearly zero over its transmission length.

To avoid sudden collapse just after a shear crack, minimum shear reinforcement is provided in prestressed concrete member in the form of stirrups. IS 1343 suggested the relation as

What is the maximum possible eccentricity in a prestressed concrete beam of circular cross-section ? Diameter of the section is d. Tension is not allowed anywhere and any time in the cross-section. Neglect dead load (self-weight).

What will be the maximum possible uniformly distributed load (inclusive of self-weight) over the entire span of a simply supported beam of span 'L'such that the deflection at midspan at service condition is zero ? The cross-section is rectangular. The prestressing force 'P' is applied with uniform eccentricity 'e'. Assume no losses.

The loss due to creep in prestressed concrete shall be determined considering

The limit state of collapse for prestressed concrete is

The designed prestressed concrete element should satisfy the limits specified for permissible stresses at transfer stage as well as service condition. The prestressing force 'P' and eccentricity 'e' evaluated from those limits are 

During tensioning of prestressing tendons the breakage of wires in any one prestressed concrete member shall not exceed 

Who is known as the Father of Scientific Management ?

ABC analysis is referred to as 

A scaled drawing of the proposed construction site showing all the relevant features such as entry and exit points to the site, storage area for materials, toilets, workers quarters, etc. is called

The event or events that immediately come before another event without any intervening events are called__________ events to that event.

Which rule is used for numbering the events in a network, scientifically?
