Questions: 32) Which statement concerning falsework removal is correct? Bookmark this question A) Removal should begin at the span ends for the full width of span and proceed simultaneously to the center of span. B) Do not release falsework until completion of the curing period. C) Removal should not occur until the concrete has reached its 45 -day strength. D) Removal should occur as rapidly as possible.

The answer is B: Do not release falsework until completion of the curing period.

Explanation for each option:

A) Removal should begin at the span ends for the full width of span and proceed simultaneously to the center of span.

• This option is incorrect because the removal of falsework should be done in a manner that does not induce excessive stress or deformation in the structure. Starting at the ends and moving to the center could potentially cause uneven stress distribution.

B) Do not release falsework until completion of the curing period.

• This option is correct. The curing period is crucial for concrete to gain sufficient strength. Removing falsework before the concrete has adequately cured can compromise the structural integrity.

C) Removal should not occur until the concrete has reached its 45-day strength.

• This option is incorrect because the specific time frame for reaching adequate strength can vary depending on the concrete mix and environmental conditions. The curing period is a more relevant factor than a fixed number of days.

D) Removal should occur as rapidly as possible.

• This option is incorrect because rapid removal of falsework without considering the concrete's strength and curing status can lead to structural failure or damage.

In summary, the correct approach is to ensure that the concrete has completed its curing period before removing the falsework, as stated in option B.
