T Mr. Joel Haack Haack Brothers Homes Plan Check Number: C2004-001, Second Building Review August 11, 2020 width is correct. The drawings should be coordinated for consistency. See IBC Section 107.2.1. Gravity System: 8. This comment has not been addressed. The original comment stated that the framing plans should specify hardware connections for the beams, headers, and joists. The provided response does not appear to address the comment. The plans do not appear to provide the required connection hardware. See IBC Sections 107.2.1, 1603.1, and 1604.4. The following comments should be addressed: a. The plans do not appear to clearly show all gravity framing. The load paths cannot be verified. This includes vertical components (e.g., posts) of the system. Headers and beams appear to be missing. Joist framing appears to be required in many locations without clear specification of the framing extents and sizes. The plans should be revised to provide a complete and clear load path to the foundations. b. Connections should be specified between all framing members where direction bearing is not provided. The make and model of proprietary hardware should be stated. Lateral System: 14.This comment has not been completely addressed. Detail 14/S-2 (previously Detail 5/S-1) shows an ordinary steel moment frame. Additional calculations and details are required for this portion of the lateral system. See IBC Sections 1604.1, 1604.4, 1613.1, and 2205.2.1.2. The following comments should be addressed: a. The design of the column connections to the wood-framed structure are required to comply with the seismic detailing requirements of AISC 341-10 Sections D2.6a and D2.6b. Note that 2014 version of this standard may provide preferable design criteria and is permitted for use per IBC Section 104.11. b. The proposed lateral system (i.e., steel moment frame to wood shear wall) is not vertically continuous to the foundation (i.e., in-plane offset between the frame and walls), and constitutes a Type 4 Vertical Structural Irregularity per ASCE 7-10 Table 12.3-2. The supporting wood posts, and the connections between the steel and wood posts and to the foundation, should be designed including overstrength per Section 12.3.3.3. The load combinations of Section 12.4.3.2 including vertical load effects of Section 12.4.2.2 should be used. c. Continuing with the previous comment, steel column bases should be provided with collectors transferring the shear loads to the wood shear walls. The collectors and their connections to both the column bases and the walls should be designed for a 25% increase per ASCE 7-10 Section 12.3.3.4. Miscellaneous: 20.This comment has not been addressed. The original comment addressed Details 4/A5.2 and 6/A5.2 show guards and their connections to the structure. The details do not appear to include revisions as stated in the response. The calculations pages referenced in the response were not included. See IBC Section 1607.8.1.
