    Slope stability evaluation existing landslide

    bdbd, instead using the shear band, i used residual values for the soil above 6m (landslide depth),and of course without cohesion. I preferred this way, rather than a shear band, because on-site the terrain looks pretty messed up, and there is a lot of water. And yes, there may be thousand of...

    Slope stability evaluation existing landslide

    Thank you for your response, but i think i maybe was miss understood by you. 1. The lithology is the following: 0-6 m --> mobilized deluvial soil: phi = 16, determined with torsional ring shear 6-9 m --> stable deluvial soil: phi 20.5 and cohesion 5 kPa 9-20 ---> stiff clay: phi...

    Slope stability evaluation existing landslide

    Hi all, The company where i work recently got involved in design of a landslide stabilization by piles. The geotechnical report gave the following parameters for the soil profile: 1. Deluvial soil (mobilized): peak phi=20.5 / peak cohesion=5kPa, residual phi=16 and undrained shear strength =...

    Flat Slab - Punching shear

    The building is only 2 level height, and the opening is only between first floor and ground floor. When I was on site 2 days ago I managed to catch the plumber and I insisted that the opening between floor 1 and 2 to be at least 30 cm far away from column. I did a design after EC2 with the slab...

    Flat Slab - Punching shear

    Well, the opening is done and the reinforcement are already cut in the opening. Can you told me some ways of strengthening? I would consider some steel L profiles (150mmx150mmx15mm) as a collar on at least 2 sides (right and left). Do you think there is also a problem on bending moments...

    Flat Slab - Punching shear

    Hello guys, I have a question. Some relatives want to buy a new flat. - non-seismic zone (ag = 0,08 g) - build with load bearing walls on contour and with a column in middle (30cmx30cm)------> structural system is a flat slab with perimeter beams - slab is 15 cm thick, and the reinforcement...

    Raft foundation - semi-basement raft

    Well, today we managed to calculate the raft also in SAP with elastic springs (determined ks value on site-25000 KN/m2/m), which is better than we expected. As an inverted floor, we had with about 15% bigger bending moments, comparing to the ones resulted from design with elastic springs. The...

    Raft foundation - semi-basement raft

    The problem with a thicker raft, is that our project verifier (with local minister authorization) told that a raft thicker than 0,50m is surely not needed because from his point of view, for such loads, with a 0,85 cm crush stone cushion and reinforced concrete walls at basement, and considering...

    Raft foundation - semi-basement raft

    Hello to all, Finally, after a while when i was only reading, now i joined the forum and start asking. I have a dilemma with a project that our company is subjected to do. It is about a 5 stories flat building, with a bearing pressure of about 100 kPa. Because of the low bearing capacity of...
