Code requirements for load testing of concrete members of existing buildings

Modified language is states to satisfy most committee members. ACI Staff had some editorial
comments. Document now available in print. Committee 562 is presenting code document
through a series of presentations. Included in these presentations is an example of how the 437
code is used.
N. Carino asks to confirm the 562 code’s adoption to IEBC.
T. Nanni discusses new opportunity to get 562 into IEBC with committee 562’s goal of having
the document adopted in the 2018 IEBC code.
C. Larosche states that he has presented Chapter 6 of the 562 code at the ICRI convention.
Included in this presentation is the use of the 437 code through an example.
Discussion of relationship between 437/562 code and chapter 20 of 318 code begins.
Leadership of 562 and 318 committees discussed this relationship during the convention in
Phoenix and agreed that the govering code would apply. The code update 318-17 was stated to
update the clarification of governing code document, 562 vs 318. TAC recommends that a
single load test method be made between 318, 437 and 562, T. Nanni states that the term of the
incoming chair will have the fundamental task of reconciling the difference between the two load
test methods.
T. Nanni states that the primary difference between opposing viewpoints is TLM, and suggests
that a joint subcommittee be formed between 437 and 318 once a new 318 chair is introduced.
M. Lee initiates discussion of governing code and interesting jurisdiction concerns. M. Lee cites
the example of Allen stadium in Allen, TX. This stadium has been opened yet the contractor has
not been paid.
D. McCarthy initiates discussion on committee 350’s passed ballot regarding the use of the 437
code.
Discussion of magnitude of test loads required by 437 and 318 is brought up. N. Carino asks
which TLM is higher. T. Nanni states that a primary difference is 437’s use of both dead and
super dead loads which is not provided in 318.
A question is raised regarding the need for chapter 20 in the 318 code. N. Carino states that the
chapter is needed for buildings during construction, T. Nanni states that the two (TLM) should
be the same.
Ziehl thanks committee for discussion and asks that the next topic in the agenda be brought up.
