GeoPaveTraffic,
Thanks for your reply.
However, I have to do preliminary design in an exam....I think it is quite difficult to bring a computer....
Do you have any better solution?
I am looking for retaining wall design (e.g bored pile wall) charts which allow me to roughly estimate the reqired I value and embedded depth for some given conditons/parameters (i.e. surcharge, angle of friction, retained height).
Does anybody know whether such a design chart is available or...
I am working on a bridge project and the foundation is that: bored piles of 600mm diameter will rest on clalk which is covered a 12m thick soft made ground. A geotechnical engineer said "it would be difficult to lower (the bottom of) a reinforcement cage deep down to the pile base if the pile is...
tjhubo,
Thanks for your advice.
krakordian,
I just have the electronic copy. I got the file from my "boss" so I don't know where it comes from....I think you are right, this book might be published in 78's because a lot of prestressing techniques mentioned in this book was developed in the...
Has anybody read “Precast Segmental Box Girder Bridge Manual”, Post-Tensioning Institute and Prestressed Concrete Institute???
I got a question about distribution of BM after a joint is formed to connect two erected spans.
Refer to Fig 3.18 (b), Step 3 on page 39, it shows that all erected...
I'm going to design a very short span (of 9m 10m long) RC slab bridge carrying one carriageway and a footway with 3 piles at each end (spaced at approx 3.1m spacing).
Since the bridge is very very short, local effects (such as punching shear, transverse bending moment) may be more critical than...
In checking the sliding stability at intermediate levels of a gabion wall, what is the angle of friction on the interface between two gabions/baskets?
In addition, what is the unit weight of the rock fill in the preliminary design?
Thanks
Thank for all ur answers!!
In Hongkong, a lot of buildings constructed in the 70's and onwards are over 30-40 storeys. They are all (nearly 88.5%) in the form of shear wall-beam-slab construction. I just wonder what the flat slab is not commonly adopted. In the UK, there is a lot of flat slab...
Correction:
I have a question about the temperature difference load:
In Fig.11.5 of the mentioned book, all the three spans are subject to temperature load. In Fig. 11.5 (c) there is a pair of restrained moments at the ends because there are no adjacent members/internal forces (induced by the...
I have a question about the temperature difference load:
In Fig.11.5 of the mentioned book, all the three spans are subject to temperature load. In Fig. 11.5 (c) there is a pair of restrained moments at the ends because there are no adjacent members to balance them. My question is that if the...
It is a domestic boiler.
I'm not the owenr of the flat but just a tenant. However, I believe the bioler is about 5-10 years old. The boiler is not pretty big, measuring 1.75m height by 1m diameter. These dimensions include the thickness of the Insulation material....
I think the boiler hasn't...
I am a bridge engineers and want to ask a question about electric boiler....
I've moved into a new flat whiich is fitted with an electric bolier. I find it doesn;t work very well. Could anybody tell me, after swithing it on, how long I have to waited before I can turn the hot water tape?
In...
