Q

Used primarily for the design of the buildings.

A

AMERICAN CONCRETE INSTITUTE (ACI code)

21
Q

it provides explanations, suggestions, and additional information concerning the design requirements.

A

Commentary

22
Q

loads of constant magnitude and remain in one position. They include the weight of the structure and any fixtures permanently attached to it.

A

Dead Loads

23
Q

loads that can change in magnitude and position. They are induced by gravity.

A

Live Loads

24
Q

Loads that are caused by group of trucks or train wheels

A

Traffic loads for bridges

25
Q

Loads that are caused by the Vibration of movable loads.

A

Impact Loads

26
Q

An example of this load is stopping a train on a railroad bridge or a truck on a highway bridge.

A

Longitudinal Load

27
Q

Includes soil pressure, hydrostatic pressure, blast loads, and centrifugal forces.

A

Miscellaneous Load

28
Q

Loads that are caused by explosions, sonic booms, and military weapons

A

Blast Loads

29
Q

Loads that are caused by the environment in which the structure is located.

A

Environmental Loads

30
Q

Given the cross section, concrete
strength, reinforcement size and
location, and yield strength, compute the
resistance or strength and the compare
to the strength required.

there should be one unique
answer.

A

Analysis

31
Q

Given a factored design moment,
normally designated as 𝑀𝑒, select a
suitable cross section, including
dimensions, concrete strength, and solve
for required reinforcement.

there are many possible
solutions.

A

Design

32
Q

This is reached when a structure or structural element is no
longer acceptable or unfit for its intended
use

A

Limit State

33
Q

These involves structural collapse of a part or all of the structure and loss of life can occur.

A

Ultimate Limit State

34
Q

Minor local failure overloads causing adjacent members to failure until entire structure collapsed.

A

Progressive collapse

35
Q

yielding of reinforcement to form plastic hinges at enough sections to make structure unstable.

A

Formation of Plastic Mechanism

36
Q

members can fracture under
repeated stress cycles of service loads (may
cause collapse).

A

Fatigue

37
Q

Functional use of structure is disrupted, but
collapse is not expected.

A

Serviceability Limit States

38
Q

Damage or failures caused by abnormal
conditions or abnormal loadings

A

Special Limit States

39
Q

this is based on working loads, also referred to as service loads or unfactored loads.

A

Working Stress Design

40
Q

this requires that the design strength of a
member at any section should equal or
exceed the required strength

A

Strength Design

41
Q

overload factor due to probable
variation of service loads.

A

Load Factor

42
Q

load specified by general building
code (unfactored).

A

Service Loads

43
Q

Also called the Allowable Stress Design, it is a method of design based on elastic stage of a structural member.

A

Working Stress Method

44
Q

Also called the Ultimate Strength Design, it
is a method based on ultimate limit state
design.

are the initial shrinkage cracks due to carbonation shrinkage, hydration shrinkage, and drying shrinkage

A

Shrinkage Microcracks

47
Q

are extensions of shrinkage microcracks. Occur at 15-20% ultimate strength of concrete.

A

Bond Microcracks

48
Q

are microcracks that occur in the matrix. Occur at 30-45% ultimate strength of concrete.

A

Matrix Microcracks
