How do you rationalise these types of balustrade connections?

Withdrawal strength wouldn't be an issue, but I thought you need 5d edge distance for shear.
How about torsion - is this nominal and taken out by joist...
I am designing a basement that extends about 5m beneath an existing house, 4.5m deep. I am planning the design around constructing soldier piles along the perimeter of the basement inside the house prior to excavation, with a top-down shotcrete methodology.
When designing a propped or tied-back...
Hi, from my code NZS3404 for steel design, there is the requirement for minimum design actions acting on steel connections: "Connections at the end of tension or compression members - a force of 0.3 times the member design capacity". I'm looking at designing some epoxy bolts for small columns...
Hi,
Do I need to provide cover to the bottom of a rebate, or can I assume that grout will provide that cover?
I attached a sketch which might help understand the question. A little context, in case you're wondering; Essentially I have a prefab steel cage for a concrete pad which will sit...
In ETABS, for example, there is the option to import a .dxf file of architectural gridlines. Does anyone know if there is a way to do the equivalent in SAP2000? When I import a .dxf it always treats it as structural members.
Hi,
I'm using CPeT-IT, dealing with some very fine organic soils. The soils I'm interested in are determined to be SBTn = 0, which I understand to mean undefined. As a result, I cannot obtain a number of key parameters.
I've figured the reason for this: my soils have very low fs (uncorrected)...
Hi,
In the case that I have CPT data, when calculating total and effective stress, should I be taking u=9.81*z or u=u2(pore water pressure from CPT)?
Cheers,

This is in terms of a legal case with respect to the earthquake susceptibility of a warehouse. The roof structure is DHS purlins w/fastbrace (lateral restraint to purlins https://www.dimondstructural.co.nz/page/purlin/) with corrugated iron cladding. There is no cross bracing.
What does the...
Our contractors have removed temporary positioning brackets that were tack-welded to steel reinforcement by striking them with a hammer. My thinking is this wouldn't affect the integrity of the steel in any way (I have already found the tack welds alone are an unfortunate defect). What do you think?
Hi,
I have a case where the builder has constructed the connection as shown below. In this situation, would the coach screw act as a second bolt with regards to plying forces? Or should I be considering this a single bolt connection? If the latter is the case, how should one go about...

What do they mean by longitudinal splitting? Is this like the concrete splitting across the entire span? I can't seem to find any guidance on this at all.
I've got some 50kN loads concentrated in an apx 300mm2 area on a hollow core floor, which has a topping. I'm assuming the...
Hey,
I'm making a SAP2000 model for a cable stay bridge. This keeps happening:
Currently I've defined the self-weight as 0 in the loading pattern. Still, if I change the cable diameter from 0.1m to 10m, this happens:
Or if I define the self-weight as 1:
I think the question is self...
I'm using the equations from this research paper https://www.iitk.ac.in/nicee/wcee/article/WCEE2012_0490.pdf
I'm hoping to use the linear analysis as shown in the paper. What are the terms X and τ in this equation supposed to represent?
Hi, I'm trying to strengthen an existing glulam beam. I plan on nailing/bolting a steel plate to the underside of the beam. I've done calculations for the bending stresses in the glulam and steel sections; from my understanding the bolts should have to resist the difference in stress between the...
