Is anyone aware of a reference (or references) with straightforward earth retention design examples? I've come across a lot of reference materials that contain either too many pictures and written descriptions with too few actual, complete engineering design examples to use for guidance. I've...
I suggested helical piers to underpin in combination with the soldier pile/wood lagging wall in front, like you mention, but the geotechnical engineer said he is worried the helical piers have no lateral resistance and may move over time if there is any gap behind the lagging from over digging...
One thought I've had is to install a welded bracket to the back of the soldier pile support the foundation. Any thoughts?
Alternately, if I underpin, how deep do I need to go below the new excavation? The underpinning concrete column is designed for lateral loading in addition to vertical, so...
I'm designing a soldier pile and lagging retaining wall. There is an existing building (2 story house) that will be near the wall (1 to 2ft from the back). I plan to design the wall with an appropriate surcharge from the house foundation and limit the deflection of the top of the wall to...
I'm planning to add a 70'x40' mezzanine to the interior of a relatively large, existing reinforced concrete building. What is the most efficient way to approach the design, with seismic interaction of the two systems being the main concern?
Does anyone know of good references for soldier pile/lagging design with and without tieback/bracing?
I'm also looking for design examples of underpinning.
Can someone recommend good reference books or materials for underpinning design? Specifically, I'm looking for technical underpinning design guidelines for underpinning in relation to earth retention (soldier pile/lagging, etc.).
