CHAPTER 18 FOUNDATIONS AND RETAINING WALLS SECTION 1801 GENERAL 1801.1 Scope. Provisions of this chapter shall govern the design, construction, and resistance to water intrusion of 1803.2.6 Party walls. A party wall, which is in good con-dition and otherwise suitable for continued use, shall be
If the wall is restrained at the top, you would probably about 60 psf/ft active lateral pressure and 1 foot of surcharge is equiavalent to 1*60 = 60 psf lateral load along the wall height. RE: Basement/Retaining Wall Surcharge
Basement Foundation Wall The basement foundation wall Figure 1e may act as cantilever retaining wall. The first floor may provide an additional horizontal reaction similar to the basement floor slab, however, thereby making the wall act as a vertical beam.

The surcharge can be 2 feet or more of earth surcharge, but 250 pdf minimum. I don't have my AASHTO manual right now moving my office so I can't look it up for you. I'd say the load is a permanent load on the wall.
Earth Pressure and Retaining Wall Basics for Non-Geotechnical Engineers Richard P. Weber Course Content wall from earth pressure, surcharge load, water, earthquake etc. Prior to completing any The wall could be a basement wall, retaining wall, earth
Driveways, parking lots, equipment, etc, are examples of surcharges in a basement wall. A uniform surcharge will produce a uniform lateral pressure on the wall. A roadway running parallel to the wall may be modeled with a Strip load, and it may be calculated using the Boussinesq approach.
DETERMINATION OF EARTH PRESSURE DISTRIBUTIONS FOR LARGE-SCALE RETENTION STRUCTURES J. David Rogers, Ph.D., P.E., R.G. Geological Engineering Problems with backfill construction operations or techniques have led to many retaining wall failures. The effects of the surcharge load imposed by construction equipment must be adequately
If the retaining wall is, for example, the basement foundation wall of a building, then it likely has a beam or other lateral support at the top as well as the cantilevered support at the bottom. H L is the total pressure behind the wall due to live load surcharge if present . H P is the total passive earth pressure in front of the wall. W
Basement Walls A basement wall is a type of retaining wall in which there is lateral support assumed to be provided at bottom and top by the basement floor slab and first floor construction, respectively. As previously mentioned, the wall would be designed as a simply supported member with a loading diagram and

Any added weight above a retaining wall is called a surcharge. Patios, swimming pools and driveways are common residential surcharges. Your wall may need additional support if a surcharge is present. Setback. The amount your wall leans into the hill is called setback. AB blocks come in approximate setbacks of 6 and 12 .
This chapter deals with earth pressure and hydraulic pressure acting on exterior basement walls of increase in earth pressure due to surcharge on the ground surface behind the retaining wall kN/m2 q acting earth pressure and hydraulic pressure are principal loads cannot be precluded. By the same

SECTION 5 - RETAINING WALLS Part A . General Requirements and Materials . 5.1 GENERAL . Retaining walls shall be designed to withstand lateral earth and water pressures, the effects of surcharge loads, the self-weight of the wall and in special cases, earth quake loads in accordance with the general principles specified in this section.
BASEMENT RETAINING WALLS AND CANTILEVERED SITE RETAINING WALLS 12-FEET OR LESS IN HEIGHT, AS MEASURED FROM THE TOP OF THE FOOTING, DO NOT REQUIRE A back face of the wall shall be considered as a surcharge. 5. The resultant of all vertical loads and late ral pressures shall pass through the middle one third of the footing.
As an example, lets consider a basement wall in a building, which is a restrained retaining wall with a level backfill, subject to the traffic surcharge load shown. Apply a vertical concentrated load on top of the stem as a reaction of the upper levels of the structure. The water table occurs below the wall footing.
Surcharge loads Acting on Retaining Wall. Surcharge loads acting on retaining wall are additional vertical loads that used to the backfill soil above the top of the wall. It can be either dead loads for example sloping backfill above the wall height or live load which could result from highway or parking lot, paving or adjacent footing.
