surcharge loading on retaining wall

Regarding surcharge loads on retaining wall, I've notice that, in some instances, a factor of,ie, Ka =1/3 was multiplied to surcharge loading, while others do not have any. I've checked some references ISTructE example do not have any "factor" while "Structural Foundation Designer's Manual Curtins " have one wKa, pp 307 .

Geotech-Retaining Wall with Surcharge Load

Helpful retaining wall problem with a surcharge load. Great geotech type problem for the PE exam Head to www.civilengineeringacademy.com for more including a great practice exam. Here's the link

Lateral Pressures on Retaining Walls Due to Backfill

Lateral Pressures on Retaining Walls Due to Backfill Surface Loads M. G. SPANGLER, Research Professor of Civil Engineering, and Experiment Station, Iowa State College For many decades the traditional method of evaluating the lateral pressure on a retaining wall due to a load applied at the surface of the soil backfill surcharge load.

751.24 LFD Retaining Walls

Retaining wall shall be designed to withstand lateral earth and water pressures, including any live and dead load surcharge, the self weight of the wall, temperature and shrinkage effect, live load and collision forces, and earthquake loads in accordance with the general principles of AASHTO Section 5 and the general principles specified in this article.

Basement Wall Design Example Using ASDIP RETAIN

Example. 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.

Worked Example 2 Design of concrete cantilever retaining

Design of concrete cantilever retaining walls to resist earthquake loading for 1.2 Example Wall . Figure X.2. Concrete cantilever wall example. geometry developed for the gravity case and including the earthquake inertia loads from the self-weight of the wall and from the soil above the heel according to the analytical


DESIGN AND DETAILING OF RETAINING WALLS. 3 Gravity retaining wall GL1 GL2 Retaining walls are usually built to hold back soil mass. However, retaining Eccentricity of the load = e = b/2-x b/6 Design Example Cantilever retaining wall.


DETERMINATION OF EARTH PRESSURE DISTRIBUTIONS FOR LARGE-SCALE RETENTION STRUCTURES The actual load imposed on a semi-vertical retaining wall is dependent on eight aspects of its construction: Live or dead surcharge loads above and/or behind the wall.

FINAL Duevel AREMA Retaining Wall Design for the Railroad

Large surcharge loads are induced on retaining walls in close proximity to track. For retaining wall design, the applicable train live-load surcharge is the Cooper E80, which can be approximated as 1,880 pounds per square foot per foot psf/ft of rail. For comparison, this surcharge is significantly larger than highway live load surcharge,

Point load surcharges applied at a setback distance

A 15 ft Retaining Wall with a 16 thick footing H=16.33 has a point load surcharge of 4 kips at 21 ft setback x=21 . Most designers will say X > H, so there is no surcharge influence. Looking at the chart above, you can see 20 psf surcharge.

Loads and Forces Acting on Retaining Wall and Their

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.

Calculation of Factors of Safety Against Overturning and

In this post, I will go over the third example in our foundation design course covering retaining walls. The goal of this foundation design example is to calculate the factors of safety against overturning and sliding for a cantilever retaining wall with uniform surcharge loading.

Retaining Walls Under Seismic Loading

RETAINING WALLS UNDER SEISMIC LOADING Vijay K. Puri Professor Civil Engineering This is generally enough for static loads. During seismic loading, the retaining walls tend to get displaced from their original position. The performance of quay walls d uring Surcharge, q Inclination of the wall face, D Depth of tension cracks, H c. Paper


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.

Principles of Retaining Wall Design

Figure 2:- Tall Retaining Walls . Retaining Wall Design Considerations. Normal Loading = static earth pressure water pressure pressure due to live loads or surcharge. In general, For example, the buildings with shallow foundation may be taken as a uniform surcharge of 10kPa per storey.
