Yes. Preheater Tower that I have to design is a concrete structure that support different equipment of cement industry. (as also shown in pic that you uploaded in your previous comment.But your pics shows that it is steel structure truss and I have to design concrete structure with same equipment)
-
It is not look like as you are thinking. It is concrete structure not steel structure. Yes, I contacted with vendor also. they are saying that maximum of 305KN vertical Dead load and 100KN vertical live load are present in this structure at one story. I just want to ask that how I apply loading in ETAB. means it is uniform loading in dead load (Static load cases option) or vertical point load. Because, these tower crossing from slab's opening in the structure.
-
Dear All, Is there any one who know, how to design Pre-Heater tower of 80m height of any cement factory in ETAB? Means what type of forces will apply in ETAB? What will will live laod and dead load apply in ETAB? what will be the load combination? etc I made simple model of structure, but didn't load load yet.. I am waiting your kind reply
-
ok. Thanks Mr. Umar
-
Thanks Mr Uzair; above links are very informative. It will InshAllah definitely help me. Secondly, how to do calculation for welding of bars when cage of pile is lifting? and how to define lifting points on cage? Thanks you very much.
-
Yes. i understand what you said above.. you have any example or material regarding this?
-
I have to provide calculation with drawing: 1. welds definition (calculation), 2. The hooks that will hang the rebar cage on the casing during concreting. I have to provide dimensions and weld definition. 3. Definition of stiffeners inside the casing. : position of stiffeners and dimensions and weld definition. 4. Definition of lifting points
-
Thanks Mr. Umer.. I got your teacher point. how we do liquefaction and heterogeneity? I didn't understand this one... (sorry for late reply..)
-
Dear all, Any one design hooks and stiffeners for pile cage for lifting from crane? and necessary welding calculation and specification according to Code and standard regarding this. or any one have any documents or data regarding this issue?
-
Thanks your link.. In this doc. some statements mentioned about reclaimed soil. do u have any example related this?
-
Dear All, is there any idea, how to design foundation on reclaimed soil above sea... Building is warehouse... If it required pile foundation, then what will be the depth of pile foundation... or any other idea...
-
ok. thanks.. This data is not enough. But i try my best to do this..
-
structural design.
-
Dear All, Any one know about steel sheet pile design? is there any software do you have or any excel sheet regarding this? kindly share with me.
-
Dear you designed helipad? kindly share your detail...
-
Dear: I also never design helipad. But , I have some material regarding this. see attached file. When you designed helipad, kindly share your knowledge or models or drawings in this forum. File with name " Workshop2011" is more effective for new user on this topic. HELIPORT DESIGN AND PLANNING.pdf HELIPAD_Loads on Helicopte.pdf 1607.docx chapt04.pdf

Thanks ....for your cooperation

Is there any suggestion or recommendation?
-
Only two towers with three cables. But middle cable is main cable, and chair lift moves to and fro with this cable. Other two cables are supporting cables. (Like tricable gondola). Chair lift will not moves 180deg when it reaches to tower. Clint want to construct , just one plate form near towers, and chair lift will moves up again.

1)Design Criteria: I am using following code a. ACI b. LRFD c. ANSI 2)Expected Load on Structure: · Structure comprises of two truss tower with 2250ft apart. And 204ft level difernece. ( as shown in PDF drawing that I sent to u before.) · Two truss tower are connected with cable. · Weight of chair lift is 2000KG · Total number of passenger are 12. · Cable is eccentric. But I model cable on RISA-3D software kindly check( see attached file) 3)Possible limit states: · I didn’t design upper structure yet, how can answer your question about piling or foundation. · Seismic Zone-2B (SPC-C). · Site class= C · Wind is 120mph. · No any structure is near by. · Water table is 10ft below NGL. · Soil is not subjected to forest heave. · 1st upper structure will clear , then I will design pile foundation for that tower with Machine room. · I just did all in software.

I dont have any drawing yet. Two towers supporting chair lift like in murree. two towers are 2280 ft part , below river is flowing. I have to design towers as well as the foundation of towers.
-
I want to design a foundation for high tension cable tower for seismic. Can any one have experience about it and have any related material? kindly share with me. Towers are 150 ft in hight. Also design both towers which are 400ft apart.
