I am designing a three-sided billboard as shown in a stock image below:
It's 12 m (39 ft) tall, the width and height of one face is around 4 m (13 ft), and the peak wind pressure is around 1,6 kN/m2 (33 psf), nothing fancy.
I would like to know how to calculate the wind pressure under...
Hello
I am designing a structure for a 2-storey shopping center.
The dimensions are:
- Hollowcore slab span 8,0m (26ft).
- Inverted Tee beam span 12,0m (39ft).
- Live load 5,0 kN/m2 (100 psf).
I dont have much experience with a precast concrete, so I went out and looked around existing...
Hey guys
I am designing a connection between a precast concrete parapet and a precast balcony slab on a 19 storey residential building.
The load bearing structure of the building is mostly monolithic concrete.
INPUT INFO:
- Parapet thickness 130 mm (5.11 in)
- Balcony slab thickness 190 mm...
Let me get right to it:
Problem:
- You have a elevation jump in a monolithic concrete slab (ceiling), or a Z-shape section if you will.
- You want to detail a reinforcement for hogging bending moments M1 and M2 (perpendicular to the "jump beam").
1) I have done this detail before using...
Greetings
How do you go guys consider the connections between a monolithic concrete slab and a external concrete wall in terms of rigidity (for example as bellow):
You design them as rigid, semi-rigid ?
I know in masonry wall connections, the rigidity is decided by the "clamping" vertical...
Hello all.
I am evaluating an existing 3 storey steel frame structure with a composite slab (see attached floor-plan section).
As per usual, structural documentation is not available, and the information I gathered is as follows:
• Steel profiled decking, thickness circa 3mm (1/10 inch)...
Hello everyone
I'm looking to dive into a self-study session on Precast concrete panel systems for apartment buildings.
The name of the game is pinned connections (I imagine).
What I am looking for (hopefully) is :
• Guidebook for structural design.
• Any publication on structural...
Hello everyone.
I am designing an opening in a existing hollow core slab (HCS).
Opening dimensions are 2,0 x 2,0 m (see attachment). There are no drawings for the structure, height of the section approximated 220 mm.
Luckily the owner of the property is open to installing a new steel frame...
