Dear colleagues,
I have a particular question regarding reinforcement detailing per AS3600. In a non-seismic beam-to-column connection, should a certain percent of the bottom reinforcement in midspan be anchored behind supports or we can use separate column bars and splice them with the bottom...
Dear colleagues,
I am working on a steel project and am struggling with the recurring question whether (and when) the roof sheeting provides lateral restraint to the top flange of the purlins when calculating for gravity loads assuming the purlins work as single-span pinned beams.
Our code...
Dear colleagues,
I am analysing a one-storey structure, that consists of precast RC columns, fixed in both directions at base, supporting precast prestressed beams spanning in one direction. Beams-column connections are pinned. The roof is made of T panels, and there is space between panels so...
Dear colleagues,
I have to design a rectangular frame 10m/3m (33ft/10ft) that will have a vinyl advertisement on it, it will be vertical and the big dimension is the height. I am not allowed to connect (e.g. tie) the fabric in intermediate lines of the frame, only on the edges. It would be easy...
Dear colleagues,
I am working on a project that requires me to have a general overview on the structural building codes governing in the Sulatanate of Oman . This includes codes regarding the design of reingorced concrete structures, steel structures and of course seismic design code and...
Dear colleagues,
I received a call from a client who has removed a 25cm (10") unreinforced masonry wall in his apartment. This wall is between two columns, the clear width is 3.60m (11ft 10"), there is an unreinforced door opening 90cm(3ft) wide on one side of the wall, which makes 2.70m(8ft...
Hi,
I have to design a column made of three steel pipes (5" diameter each), that will be loaded by biaxial moments and compressive force. As a cross-section the pipes will be placed in the tops of a equilateral triangle and have clear space between them about 4-5". I intend to provide...
Hallo to all,
I am currently working on a project in which we have an existing reinforced concrete building (moment frame) which must be changed entirely from the inside. It is a five-storey two-bay (10m+5m) frame in the short direction (15m) repeated at 4-5m intervals to get a rectangular...
Hallo community,
I am working on a single level structure that consists of a system of moment frames (braced in longitudinal direction). The roof is covered with trapezoidal sheeting supporterd directly on the beams of the frame (on the top flange).
The sheeting is placed in such a way that the...
Hi community,
I would like to enhance my knowledge in designing staircases of different types - there seem to be many forms of staircases we meet in projects, but I believe they all can be groupped in several types - like single/double flight, open well, helicoidal... The other grouping is...
While reading AISC Design guide 1 - Base Plate and Anchor Rod Design (2ed) I came up with the anchor pullout failure. There are tables 3.1 and 3.2 that show anchor strength (steel) and anchor rod pullout (concrete) capacities for anchor rods with heavy hex nuts. Comparison shows that for rod...
Hallo community,
Being involved in calculations and drawings mainly I become curious how some of the member properties were chosen by the senior engineers before starting desing calculations.
I am looking for a guide that contains recommendations how to pick initial member dimensions in the...
I expected to find more topics on that but it seems I did not find the correct keywords to search for, so I will ask again.
I have been asked to recommend software for preparing the drawings of a civil engineering shop. Since the plans are 2D it seems that many of the features of the complete...
I am reviewing some drawings and there is a thing that worries me. Please excuse my bad technical english.
Rhere is a cantilevered column loaded with moment and shear and almost no axial force. The load is from one side only (no earthquake analysis). The moment couple is from forces of about...
While reading this SteelTips:
Common Steel Erection Problems and Suggested Solutions
I found that lot of the problem statements and solutions were backed by data taken from a referred SteelTIPS:
"Steel Connections/Details and Relative Costs"
(Steel TIPS), The Steel Committee of California...
