NEWTON |
The basic S.I. (System Internationale) unit of force. |
|
LOADS |
It is the general term applied for all forces which act upon a structure and anything else which causes stresses or deformations within a structure or part thereof. |
|
DEAD LOADS |
It is a term applied to the weight of the materials of construction that is the weight of the beams, girders, flooring, partitions, etc. |
|
FORCE |
The quantity that tends to accelerate or change the movement of a body. |
|
LIVE LOAD |
It refers to the occupancy load (excluding earthquake or wind forces) which is either partially or fully in place or may not be present at all is called: |
|
DENSITY |
Unit weight of materials expressed as weight per unit volume. |
|
2400kg. |
Weight of 1 cu.m. of concrete. |
|
LIGHT WEIGHT CONCRETE |
What type of concrete when air-dried weighs 1900 kg/cu.m. |
|
1000kg/m3 |
Density of water? |
|
7850kg/m3 |
Density of steel? |
|
STRESS |
Intensity of force per unit area of the cross section. |
|
STRESS |
Is the cohesive force in a body, which resist the tendency of an external force to change the shape of the body. |
|
STRESS (S) |
Force(P)/Area(A) |
|
1Pa (pascal) |
1N/m2 |
|
Curing |
Allow concrete to dry slowly by keeping it moist (hydration) to attain maximum strength. |
|
WATER CEMENT RATIO |
Compressive strength of fully cured concrete is most directly related to: |
|
CEMENT |
What is the most determinant of concrete strength. |
|
SLUMP TEST |
A test of the workability of concrete wherein a conical mould is filled with concrete. |
|
PURPOSE OF STRUCTURAL DESIGN |
To select and adopt the most practical and most econimical structural system appropriate for the function and architecture of a building or structure conceptualize by an architect. |
|
TUBURAL STRUCTURAL SYSTEM |
This system utilizes the principle of the tube in resisting gravity and lateral forces. Used for small floor areas. Most effective for high rise bldgs. |
|
TUBE IN TUBE STRUCTURAL SYSTEM |
System is used for larger floor areas. |
|
RIGID FRAME STRUCTURAL SYSTEM |
System utilizes a series of frame field rigidly together at the joints to resist gravity and lateral forces. Best suited for 30 to 35 floors. |
|
RIGID |
Structural Engineering means a structural member is restrained from rotation about joint which means structural members have end-moment. |
|
MOMENT |
Force x distance |
|
COMPOSITE |
Consist of steel and concrete. |
|
CORE AND RIGID FRAME AND STUCTURAL SYSTEM |
System uses a rigid core generally at the center of the building or structure plan and a rigid frame. Core is usually made of reinforce concrete and rifid frames around it made of steel. |
|
SHEAR WALL STRUCTURAL SYSTEM |
System consist of load bearing walls capable of resisting gravity and lateral forces. Ideally overall center of gravity of the walls should be at or near the center of gravity of a building or structure. Prevent torsion. |
|
BRACED STRUCTURAL SYSTEM |
Commonly used in steel building structure where selected bays are braced for lateral loads and other other structural members carry gravity force. |
|
COMPOSITE STRUCTURAL SYSTEM |
Combination of two or more of the other structural systems. Commonly used for irregular shaped bldgs in plan. |
|
ROOF |
Is a covering of the uppermost of a building or structure. |
|
FLAT ROOF |
Common for tall bldgs where mechl equipmnt for bldg services may be installed. High water-retention. |
|
LOW SLOPE ROOF |
Ratio of roof pitch height to roof span. Less than 30degrees |
