I need the properties in order to find the effect of CFRP rods/bars on concrete beam.ie stresses induced on concrete beams. As you might probably know very well that concrete beams are traditionally reinforced with steel rods. Thanks.
This is not a new installation. Some of the occupants are already accustomed(conditioned) with the situation. But some occupants say the vibration is stronger than previously.we have asked the mechanical people to inspect the AHU and they said they need to replace some parts of the equipment. I...
If an reinforced concrete frame structure, two to three spans, in one direction and the same in the other direction are subjected to vibration due to air-handling unit, causing discomfort to the occupants, what actions do we take? The building is a 3-storey r.c structure. The frames are filled...
Where i come from the weather is hot n wet all year round (amazon like weather). For a structure which is about 100 metres (300 ft)long by 3m(9ft) wide , is it possible to avoid expansion joint as it had always been a source of water leakages. The temp variation is 27 c to 35c.
If exp joint is a...
I have a group of 4 piles driven for a square pile cap. One of the piles failed as proven by a PDA test( Pile Driving Analysis) conducted on that particular pile.
How should I rectify the problem? Should I drive two extra piles and redesign the pile cap?Could anyone suggest any textbooks that...
Thanks for your replies.
Actually, I am asking from the viewpoint of OWNER's representative engineer.
Flame.
From your reply , who is the client, is it the owner. If so, is the client's engineer responsible for approving the design including all the liabilities thereafter.?
In a design and built contract,I have several questions
1. What are the roles of the engineer who represents the client?
2.If something is not done accordingly, what actions should the engineer(client's rep) take?
3.Is it a must that the contractor engage a consulting engineer?
Hope this...
I was arguing with my fellow engineers (all novices) about the definition and function of expansion joint.He was suggesting that the prime function of the expansion joint is it acts as a temporary separator between two concrete surfaces during construction. To me he was implying that even if...
I would like to know if a slab/structure is designed to take 2.5Kn/m2 imposed load , is it ok to use that area as a cyber cafe? What about shops?This structure is situated at an airport departure lounge.
I would like to know what is normally practised in your construction industry regarding who should do piling records . Is it the piling contractor or the engineering consultant? who should sign the records? During payment claims are photocopied piling records acceptable?
1.to modify the frame panel to be rigid, do i need moment connection and
2.to relocate the bracing , could it be just the side bracing
3. ishvaag, can u elaborate more on adding truss to the column, please
thanks
I am working on a renovation project of an existing steel structure. The structure is of portal frames spaced at about 4.5 metres and the column clear height is about 6 metres. The architect wanted to have a mezanine floor inside this existing one storey structure. The problem is the architect...
