NCMA’s Design Manual for Segmental Retaining Walls. The importance of raw material certification is discussed in this article. The article also presents a real-life scenario that contains structural steel and outlines to engineers, specifiers and owners what is required in order to ensure the long term durability performance of polyester (PET) geogrids.

Sketches of the retaining wall forces should be considered to properly distinguish the different forces acting on our retaining wall as tackled in the previous article, Retaining Wall: A Design Approach. Based on our example in Figure A.1, we have the forces due to soil pressure, due to water and surcharge load to consider. Figure A.3 below is This Guide, Segmental Retaining Walls Best Practices Guide for the Specification, Design, Construction, and Inspection of SRW Systems, is published and maintained by the National Concrete Masonry Association (NCMA) Since segmental retaining wall systems were first introduced in the 1980s, there has been a continuous evolution and
Retaining walls are, and should always be viewed as load bearing members first, and aesthetic groundscapes second. Segmental Concrete Retaining Wall Design. Retaining wall design and wall type selection is driven by several factors. These factors include cost, required wall height, ease and speed of construction, ground water conditions and Section 32 32 23 GRAVITY SEGMENTAL RETAINING WALL Guide Specification – Gravity SRW Page 1 of 12 January 2016 established in NCMA’s “Design Manual for Segmental Retaining Walls”.] .2 Submit the technical data sheet of the retaining wall components according to section [01 33 00 - submittals]. .3 Submit a manufacturer’s certification, at least [30] days before start of SRW
Aesthetic elements surrounding a particular retaining wall are key to public acceptance of a wall project. Early in the wall-design process, all comments about the wall generated from public meetings shall be reviewed during the preliminary design and environmental-documentation process. Where possible, such comments shall be considered in the SEISMIC DESIGN OF SEGMENTAL RETAINING WALLS TEK 15-9A Structural (2010) INTRODUCTION This TEK describes a method of analysis and design for conventional and geosynthetic-reinforced segmental retain-ing walls (SRWs) under seismic loading. The methodology extends the approach for structures under static loading to simple structures that may be required to resist additional dynamic loads due …
FHWA has mandated all retaining walls be designed using LRFD after October 1, 2010. It is our opinion that the NCMA design manual represents a comprehensive approach to Segmental Retaining Wall (SRW) design but tends to confl ict in principal with existing methodologies such as those originally Section 32 32 23 REINFORCED SEGMENTAL RETAINING WALL Guide Specification – Reinforced SRW Page 1 of 14 March 2016 [NOTE TO SPECIFICATION WRITER: This guide specification for the use of reinforced segmental retaining walls was developed based on the use of an aggregate or unreinforced concrete leveling pad.
