Notes to Table 2310

Note 1.

Notation FS is the allowable maximum fiber stress for the assumed grade as established by this code in section 2309.2.2 F’s (“operating” stress) is the modified allowable maximum fiber stress which may be used in the span tables and for calculating required lumber sizes. F’s is found by multiplying Fs by the factors given in the table

Note 2.

Table Columns

Column 1

Is the nominal commonly used lumber size

Column 2

Is a list of actual sizes of the supplied lumber

Column 2

Lists the sizes on the basis of a constant thickness and a width increasing by one quarter of one inch (1/4”) and one half of one inch (1/2”)

Column 3

Gives the multiplier for increasing the assumed allowable stress (Fs) based on the increases in width as listed in Column 2.

Column 4

Gives the multiplier for increasing the assumed allowable stress (Fs) based on increases in thickness

Note 3

Example: Fiber stress for assumed grade = one thousand (1,000) psi – Actual size 3-1/8 x 9-3/4

Nominal size 3 X 10

1. Multiplier factor for Width =

1.05

3-1/8 = increase of 5/8” total

2. Multiplier factor for Thickness=

.20


3.Operating stress F’s = 1.25 x Fs F’s = 1.25 x 1,000 = 1,250

Sum = 1.25

Therefore, F’s = 1,250 psi is used for calculations and in the span tables

Chapter 00 N/A
Subchapter 00 N/A
Part 1 RISBC-1 Rhode Island Building Code
Type of Filing Amendment
Regulation Status Inactive
Effective 02/01/2022

Regulation Authority:

R.I. Gen. Laws § Chapter 23-27.3

Purpose and Reason:

RISBC-1 State Building Code sets forth the requirements for building structures in Rhode Island.    Rhode Island Building Codes are amendments to the International Building Codes which we use as our model.  The State Building Code Standards Committee has reviewed this regulation and proposes the following non-technical amendments as described below:   

·         Numerous punctuation and grammatical changes have been made throughout that do not result in substantive changes to the regulation.

·         All references to International Building Code (IBC) 2015, have been changed to the 2018 edition.  Some IBC section numbers have been amended to conform to IBC 2018.

·         Throughout the regulation: updated internal cross-references with new RICR citations and references to the 2021 version for all Parts in Title 510 being amended this year.

·         Chapter 1: Administration, § 101.4.8 Swimming Pool and Spa Code. Adds to the administration chapter the requirement that SBC 14, (Part 14 of this Subchapter) shall apply whenever the International Swimming Pool and Spa Code is referenced. 

·         Chapter 10: Means of Egress.  Deleted IBC § 1010.1.4.4 and substituted language pertaining to egress doors in Group E and B occupancies which requires the installation of intruder locks.

·         Chapter 16, Section 1608.1, Replaced Table 1608.1 with new Table 1608.1 referencing the pertinent changes made in the 2018 IBC.   

·         Chapter 18, Soils and Foundations, Deletes IBC § 1801.3 and substitutes § 1809.5. This change aligns with the 2018 IBC but contains no substantive changes to the regulation.

·         Chapter 34 – Existing Structures
