It can be often misunderstood whether Truss Designers have the responsibility to seal a Truss Placement Diagram (TPD). The purpose of this Research Report is to provide the relevant code sections from the International Building Code (IBC) and the California Building Code for a thorough analysis and interpretation.

The goal of this Research Report is to assist in designing safe buildings economically, especially when sprinkler systems are required or desired in the design.

It can be often misunderstood whether a Truss Design Engineer has the responsibility to seal a Truss Placement Diagram (TPD). The purpose of this Research Report is to provide the relevant code sections from the latest editions of the International Building Code (IBC) for thorough analysis and interpretation, as they relate to the state of Texas.
Recent ASTM E119 testing (using 100% design load conditions as required by that standard), conducted independently by Underwriters Laboratory (UL) and NGC Testing Services (NGC), confirm that an unprotected floor assembly constructed of 2x10s or Flak Jacket coated I-joists do not provide “equivalent performance” to a floor assembly that has a ½” gypsum wallboard membrane ceiling as prescribed by

All building codes provide provisions for the attachment of structural sheathing to wall and roof framing members. In almost every case, the published capacity of the sheathing and fasteners assume the head of the fastener is flush with the surface of the sheathing. This Research Report discusses guidance when fasteners are overdriven.
Both the International Residential Code (IRC) and the International Building Code (IBC) require that the top plates of exterior braced wall panels be attached to the rafters or roof trusses above. This report will discuss the code requirements and provide alternate engineered designs and capacities, including heel/bird blocking, partial height blocking and blocking panels.
This Research Report reviews pertinent sections of the 2006, 2009 and 2012 International Residential Code (IRC), the 2012 IRC Commentary, and additional sources in an effort to compile the related data and identify discrepancies or omissions. The focus is catered toward meeting and better understanding the requirements for conventionally framed roofs and roof truss construction per IRC Section R802.

This report will explore some special floor loading issues that are not specifically mentioned in the building codes and require special attention to ensure that the floor system is properly designed with no serviceability issues. The following are the major issues that will be discussed: stone/ceramic tiles, large concentrated loads and floor vibrations.

Fire endurance ratings may be mandated by code for many assemblies in both floor and roof framing systems. This Research Report discusses methodologies to calculate 2-hour fire endurances of a given assembly.
After the two homes were fully framed and dried-in, the thousands of images collected were analyzed to determine the man-hours it took to complete each discreet framing task and how much waste was generated in the process. The results of the Framing the American Dream study are conclusive: The component-framed house required 152.1 man-hours to complete, whereas the stick-framed house required 373.5 hours. It took two and half-times longer to construct the stick-framed version of the floorplan.
Background:
R501.3 (IRC-12) or R302.13 (IRC-15) states the following – “Floor assemblies….shall be provided with a 1/2-inch (12.7 mm) gypsum wallboard membrane…… or equivalent…….
SBCA has compiled the articles below to provide a comprehensive guide to the information it has published on R501.3 (from the 2012 IRC) and R302.12 (the same language incorporated in the 2015 IRC). The goal in organizing the information in this way is to enable the reader to fully understand this issue and SBCA’s position.
Question: Why was the IRC changed to provide a 2x10 exclusion from the requirement in R501.3/R302.13 that states, “Floor assemblies….shall be provided with a 1/2-inch (12.7 mm) gypsum wallboard membrane”?
