Loxton south Australia. Thanks JAE

Hello I am looking at a roof layout(about year 1974) with C812 purlins. Has anyone any span tables or dimensions of this C812 purlin? Would appreciate your comments.

Thanks thaidavid40 and CAB for your comments. The softwares I will be using are capable of lengthening/reducing or keeping the cables original lengths (ie straight line between the anchor points). However the cantenary of the cables will induce forces. I managed to download a couple of papers...

Hello all I am asked to review a 50 m high guyed lattice mast with 3 vertical chords (ie equilateral triangle) with 3 levels of guys at 120 degrees. I intend to review it to AS 3995-1994 using either SpaceGass or MicroStran which has cable and second-order analysis modules. Gravitational and...

Thanks all for your inputs. Appreciate your comments. Rgds

Australia has AS/NZS 4673 'Cold-formed stainless steel structures'. There is no code for hot-rolled stainless steel. Perusing AS 4100 'SCOPE AND APPLICATION' it stipulates 'This Standard applies to buildings, structures and cranes constructed of steel' (refer attached). Is is therefore...

Thanks for all the comments. Interesting views. This is engineering and different views are expected. My take is that conventional tanking is tried and proven when they are properly installed. However the use of polyurethanes/acrylates for waterproofing has been around for a while with...

Two photographs of corrosion of steel deckform and water leak through slab/beam. Rgdshttp://files.engineering.com/getfile.aspx?folder=ea522bf5-4bac-4d52-b318-a5301d1f6b58&file=leaks.pdf

Thanks amlinerrichard and Ingenuity for your contributions. I am in Australia. Temperature is mid 40soC in summer. I will consider the use of polyurethanes/acrylates for waterproofing as one feasible options. I will document one or more options for tender following review of report by the...

Thanks Ingenuity & DamsInc for your thoughts. They are appreciated. I am aware of the issues of corrosion and hence the intrusive exploratory works discussed. I believe I will be able to manage them. The steel deckform refers to are the steel pan deck (bondek) and are probably structural. I...

I inspected a commercial building where part of the first floor is exposed to the weather and a ground floor below of carparking area and offices. The first floor slab is partly of conventional reinforced and steel deckform concrete slabs, beams and columns. New pavers were recently installed...

I am curious how 2 DN450 HDPE pipes in two cable trays will behave when supported at 6 m centres by T-shaped cantilever posts over long distance. Being relatively large pipes with large bending radii, can the serpentine that dhengr and JedClampett described be introduced in the system by...
