Most building code requirement for lateral deflection of buildings is to limit the storey drift to H/500. However it is unclear if this limit is based on the worse orthogonal direction or the resultant of the two orthogonal directions (resultant of X and Y deflection). What is you thought on this?
We are designing a three storey wood structure that will sit on a concrete foundation. My question is, can frictional force be used to resist base shear or sliding of the structure?
We are deciding which program works better for steel design. We are going to use revit modeling and use either SAP or ETABS. Revit model will be exported to SAP or ETABS to do STEEL DESIGN. Which one is better?
I am designing a 7.0 m two storey tall HSS column and I want to brace it with the bottom chord of the strut joist at mid height to reduce effective length. My question is how do you calculate for the axial load induced in the bottom chord of the strut joist?
I am designing a simple 5.4m span steel beam that supports three concentrated loads. The client wants to put twelve circular holes with a diameter ranging from 2" to maximum 4". I am using CISC 9th edition as my reference and according to my analysis using W610x140 is good. The concentrated...
I am involve in a project where we need to design a 80 feet clear span girder truss that will have wide flange members. The girder will support a three storey wood frame for dwelling. We are going to restrain the girder with pin on one end and roller on the other. My question is the roller...
