Chapter 2

PUBLIC COMMENT 1: Change definition of “shear wall” to same as in Section 2102.1:

SHEAR WALL. A wall designed to resist lateral forces parallel to the plane of the wall.

The Commission approved changing the definition of Shear Wall in Section 2102.1. The same definition needs to be changed in Chapter 2, Definitions. Makes code consistent.

Recommend approval

Chapter 2

PUBLIC COMMENT 2: The following definitions related to seismic design were deleted in the original Mod 2677 and are deleted in Draft 2. However, the terms still appear in Chapter 2 Definitions of Draft 2 with a reference to this Section. They should be stricken from Chapter 2 as well.

          Detailed plain masonry shear wall. A masonry shear wall designed to resist lateral forces neglecting stresses in reinforcement, and designed in accordance with Section 2106.1.1.

          Intermediate prestressed masonry shear wall. A prestressed masonry shear wall designed to resist lateral forces considering stresses in reinforcement, and designed in accordance with Section 2106.1.1.2.

          Intermediate reinforced masonry shear wall. A masonry shear wall designed to resist lateral forces considering stresses in reinforcement, and designed in accordance with Section 2106.1.1.

          Ordinary plain masonry shear wall. A masonry shear wall designed to resist lateral forces neglecting stresses in reinforcement, and designed in accordance with Section 2106.1.1.

          Ordinary plain prestressed masonry shear wall. A prestressed masonry shear wall designed to resist lateral forces considering stresses in reinforcement, and designed in accordance with Section 2106.1.1.1.

          Ordinary reinforced masonry shear wall. A masonry shear wall designed to resist lateral forces considering stresses in reinforcement, and designed in accordance with Section 2106.1.1.

          Special prestressed masonry shear wall. A prestressed masonry shear wall designed to resist lateral forces considering stresses in reinforcement and designed in accordance with Section 2106.1.1.3 except that only grouted, laterally restrained tendons are used.

          Special reinforced masonry shear wall. A masonry shear wall designed to resist lateral forces considering stresses in reinforcement, and designed in accordance with Section 2106.1.1.

Same as above.

4101.6.1, 4101.6.3, 424.2.6.3,  424.2.6.6, 4101.6.6

Sections referenced should be reconsidered because of the following:

  1. APSP is a more dangerous and harmful standard; it is ambiguous and more difficult to enforce.
  2. Petitioner was not accorded due process because of the cancellation of the May 2007 TAC meeting.
  3. The Commission will exceed its delegated authority because it fails to implement a Florida-specific modification.
  4. The change will increase the risk of fatal pool accidents by eliminating critical pool safety features.

 

Watterson, delete mods 2704 – 2708.  existing code provides tertiary methods, proposals allow local officials, no Florida specific reason for changing the code.  The standards exempt water parks.  Aug 1, US CPSC, top 5 household hazards included spa and drain entrapment. 

Jennifer Hatfield, the accidents mentioned by Watterson were in pools  that were not built to ANSI standards.

Reject procedural claim due to processes in place, Consortium failed to participate in TAC meeting code modification process.

Design plan and systems approval. Plan review pertaining to installation of manufactured buildings and construction activities conducted at the site of the installation shall be conducted pursuant to Chapter 1 hereof. Plan review pertaining to construction activities occurring within the manufacturing process shall be conducted by those third-party agencies as follows: third-party agencies shall review plans in conformity with Chapter 1 hereof and the following additional requirements: If the plans are for a residential manufactured building, certification from the design professional  responsible for the plans that the structure has been designed only for erection or installation on a site built permanent foundation in accordance with this code and is not designed to be moved once so erected or installed. If the residential manufactured building is transportable in one or more sections and is 8 body feet or more in width or 40 body feet (12 192 mm) or more in length, or, when erected on site, is 320 square feet (29 m2) or more, and which is built on a permanent chassis, the manufacturer shall certify that the manufactured building has been excluded from regulation by the United States Department of Housing and Urban Development.

ESTIMATED ENERGY PERFORMANCE INDEX SCORE* =

The lower higher the Energy Performance Index score, the more efficient the home.

I certify that this home has complied with the Florida Energy Efficiency Code For Building through the above energy saving features which will be installed (or exceeded) in this home before final inspection. Otherwise, a new EPL Display Card will be completed based on installed Code compliant features.

 

*NOTE: The home’s estimated Eenergy Pperformance Index score is available through the EnergyGauge USA Fla/Res 2007 computer program. This is not a Building Energy Rating. If your index score is below 100 80 or greater (or 86 for a US EPA/DOA Energy Star_designation), your home may qualify for energy efficiency mortgage (EEM) incentives if you obtain a Florida Energy Gauge Rating.

2107.1

PUBLIC COMMENT 4: Add a sentence to provide a clear differentiation between the lap splice reference and the development length reference. This is a merely a clarification and has no substantive effect on the calculation of these requirements. Leaving as written in Draft 2 will result in confusion and may result in improper design.

 

2107.1 General.  The design of masonry structures using allowable stress design shall comply with the requirements of Chapters 1 and 2 of ACI 530/ASCE 5/TMS 402 except as modified by Section 2107.2.  Lap splices shall be in accordance with ACI 530/ ASC5/ TMS 402 or in accordance with 2107.3 or 2107.5 as specified by the architect or engineer. Development of bars in tension and compression shall be in accordance with ACI 530/ASCE 5/TMS 402 or in accordance with 2107.4 as specified by the architect or engineer.

γ = 1.2 for No. 8 (M#25) through No. 11 (M#36) bars

 

Where epoxy coated bars are used, lap length shall be increased by 50 percent.

 

Proponent is correct. This went through the Commission but is not in Draft 2 of the 2007 FBC. Corrections will be made to Draft 2.

No action needed.

2108.2

PUBLIC COMMENT 11: Delete Section 2108.2 as shown in Draft 2 and renumber Section 2108.3 as shown in Draft 2 as Section 2108.2. The Sections are duplicates and say the same thing. There has been some confusion regarding the fact that Equation 3-15 is not contained in the code. The reference is to an equation contained in ACI 530/ASCE 5/TMS 402. The Section, 2108.2 modifies Section 3.3.3.3 of the standard, but, makes no changes to Equation 3-15. This is the same as is done with Equation 2-9 in Section 2107.4 shown in Public Comment 6 above.

of intermediate or special reinforced walls or special moment frames of masonry.

3.3.3.4(c).Mechanical splices shall be classified asType1 or 2 according to Section 21.2.6.1of ACI 318. Type1 mechanical splices shall not be used within a plastic hinge zone or within  a beam-column joint of intermediate or special reinforced masonry shear walls or special moment frames. Type 2 mechanical splices are permitted in any location within a member

R4410.1

Change Section R4410.1 as shown:

 

R4410.1 General

R4410.1.1 Exterior wall cladding…through R4415.

R4410.1.2 Exterior wall cladding, surfacing…wind-borne debris. [1-2 no change]

R4410.1.3 Workmanship. Cladding…in Chapter 43.

R4410.1.4 All exterior wall cladding…shall have Product Approval.

As read, there are two Section R4410.2s in the code. Adding the .1 will make Section R4410.1 consistent with other treatment in Chapter 44 and avoid confusion. Recommend approval
