Pete The intent of Section 12.13.9.3.4 is to assure that if lateral spreading occurs, and imposes permanent lateral deformation of the pile along its length, that the pile will still be able to sustain the gravity loads imposed on it and not cause collapse. The degree and rigor of analysis...
Good Day, This is my first posting, so I am grateful for any feedback/input. We have some discussions in our office related to Provision 12.13.9.3.4 in ASCE 7-16, in particular: Is the intention of this provision such that the engineer is to perform a p-delta analysis with secondary effects on...
The only load that need be considered for a pipe submerged within a basin i the inertial seismic load on teh pipe (and its contents) alone. Convective and impulsive loads, important to design of tank shells are not applicable to pipes within the basin. This is becasue the pipe is surrounded by...
I am looking for some clarification regarding the seismic load calculation for a pipe support anchorage design. The scenario is a pipe submerged in a water-filled concrete basin which is located in a high seismic region and experiences sloshing. In such a scenario, I understand that the pipe and...
If you are truly concerned about the building's performance, then use ASCE 41 and upgrade the entire building to conform to appropriate performance objectives. Otherwise, just use ASCE 7 and conform to its requirements. -- Ronald Hamburger, SE Consulting Principal Simpson Gumpertz & Heger --
Ronald, thanks for your feedback. For your point no.1: The use or selection of R is relevant to the seismic design category which is classified as "D" for the addition & this requires to comply with Table 12.2-1 ASCE for the selection of seismic force-resisting system which also will end up...
Almontasir - You are correct that under ASCE 7-16, upgrade of the entire structure would not be required, assuming that the new addition conforms to the applicable requirements of ASCE 7 for new construction and that the demand on existing elements of the structure does not increase by more than...
Dear valued ASCE team & members , Kindly we need your kind technical advice on the following case of study: The case is an existing building located in Abu Dhabi-UAE which was designed as building frame system (ordinary shear wall system) & as per old design code seismic parameters,...
