A

Combined stress member

70
Q

A design for reinforced concrete beam that will cause the limiting stresses in the concrete
and steel bars to be reached simultaneously, causing them to fail at the same time

A

Balanced Design

71
Q

A design in which the steel reinforcement is lesser than what is required for a balanced
design. It causes the steel bars to reach its limiting stress first while the concrete remains under
stressed. Once ultimate load is reached, large cracks become visible in the tensile zone of
concrete and will give warning to the occupants to decrease the load.

A

Under Reinforced Design

72
Q

A design in which steel reinforcement is more than what is required for a balanced
design. When the ultimate load is reached, the compression zone of the concrete is highly
stressed leaving the steel bars under stressed and failure occurs suddenly without warning to the
occupants of the structure.

A

Over Reinforced Design

73
Q

is a jointed frame that is used to support loads over a relatively long span. In
general, the loads are applied to the it in a direction transverse to its length and the loads
are applied only at the joints.

Truss

74
Q

outer truss members

A

Chords

75
Q

are the interior members of truss

A

web members (diagonals and verticals

76
Q

A

Bays

77
Q

A

Purlins

78
Q

portion of the truss that occurs between two adjacent joints of the top chord

A

Panels

79
Q

This type of trusses is used where high rise and floor spaces free of obstruction are desired. Its
more frequent use on frames is to provide large hay-storage space over dairy stables and
storage space in machinery sheds and similar structures.

A

Arch

80
Q

This is especially adaptable to structures in which the walls are subjected to outward
lateral pressure due to contained liquid or semi-liquid material. The silo, water tanks and the
circular grain bin are the common examples.

loads on the building are transmitted to the ground.

A

Foundation

82
Q

weight and which resist side pressure from wind and, in some cases, from stored
material or objects within the building

A

Masonry wall

83
Q
  • wall is built of a material placed in forms during the construction.
    Examples are traditional earth wall and the modern concrete wall
A

Monolithic

84
Q

essential part of any building in that it provides the necessary protection
from rain, sun, wind, heat and cold.

A

Roof

85
Q

used only to a limited extent on farm buildings. Maintenance is high since the
roof has little slope for water to run off

A

Flat roof

86
Q

the simplest and easiest to construct and maintain. It is common sight on
single story poultry houses, open sheds for cattle or swine, and similar buildings

A

Shed Roof

87
Q

one of the most universally used roof shapes on farm buildings. This type of roof is commonly seen on two-story poultry houses, dairy barns, and single-story buildings
that are too wide for shed type of roof.

A

Gable roof

88
Q

more desirable from an architectural standpoint than from utilitarian value. It
requires more complicated framing than the gable roof and is consequently more expensive
to build. One of the most common uses of this is on garages.

A

Hip roof

89
Q

used to gain more space for the overhead storage of hay and feed. This
roof is common sight on two-story dairy barns and other livestock shelters where overhead
storage of hay is desired.

A

Gambrel

90
Q

wall is constructed as a sandwich of two thin skins or sheets of
reinforced plastic, metal, asbestos-cement or other suitable material bonded to a
core of foamed plastic to produce a thin wall element of high strength and low
weight.

A

Membrane wall

91
Q

also known as gothic roof. Prefabrication of laminated arched rafters has
made the construction of this roof simple and easy. Its uses are the same as for the
gambrel roof.

A

Arch roof

92
Q

provide light and ventilation in a building an allow those within to view the
surrounding landscape and observe the activities in the farmyard

A

Windows

93
Q

General Considerations in Planning Livestock Housing

A

Site and location
Space, feed and water requirement
Suitable environment to maintain highly productive condition
Maximum efficiency of labor condition
Sanitary condition

94
Q

In this farmstead type, all structures are in close proximity, in many instances, will
all or most of the buildings joined together or connected by sheds or covered walks.

A

Concentrated

95
Q

It often consists of two or more separated groups of buildings;
one group includes the residence, garage and attendant service buildings; the other
group includes barns, storage houses, and principal service buildings and workers’
houses.

A

Plantation or Ranch

96
Q

consists primarily of residence and small service buildings, where the
essential farm operations area carried on with hired services.

A

Suburban type

97
Q

This is the most common type of farmstead where buildings are
located sufficiently far apart to allow adequate room for road drives and yards,
reasonable fire safety, and sanitation, yet sufficiently close together to be effective
for farm operation.

A

Distributed type

98
Q

is the ability of a material to absorb or damp vibrations, which is a process of absorbing kinetic energy of vibration owing to hysterisis.

A

Damping Capacity
