AERZ consulting Inc. has inspected structural integrity of a house after removal of wall by contractor at Sundance area in Calgary, Alberta. Luckily removal of wall did not affect the house and the wall was not a bearing one. It is important to consult a structural engineer before removal of walls in your house. The contractor installed a beam after removal of wall which will tie the remaining walls and keep the lateral resistance intact. It is important not to engage the beam in carrying the roof loads if wall removed was not a bearing wall. It is expected that roof might deflect under snow loads during winter and causes over-stress in the beam and bearing studs.
3D STAAD PRO model after addition of new make up air conditioning unit of a commercial building in NE of Calgary. The open web steel joists are HSS steel sections with bracing of bottom chords at the middle and end of roof trusses. The roof was safely capable of carrying the new air conditioning unit.
A previous steel farm building is structurally assessed by AERZ Consulting Inc. using current Alberta building code to change building occupancy and use. The building is 41 ft long by 33 ft wide by 20 ft ridge height. Building and foundations were assessed at the Municipality of Foothills in Alberta; very close to Calgary city limits. The main building steel frames are tapered welded wide flanges while purlins and girts are cold formed Z sections. Dead loads, snow loads, wind and earthquake loads were applied to the building and building elements checked against such loads and there load combinations. The structural analysis and design checks were performed using STAAD PRO software.
AERZ civil structural consulting Inc. has done structural assessment of a commercial unit roof at south east Calgary. The owner of the commercial wanted to add a new heavy HVAC unit on top of the roof. The structural assessment found that the roof will not be safe by 25% if the HVAC unit will be installed on the roof (25% over stressed than allowable design values). The roof trusses are wood steel open web trusses with steel tube sections as vertical web members and wooden upper and lower horizontal chords held together by pins. An Engineering solution was provided to owner to support the roof trusses carrying the HVAC unit.
