ACI 350.3-06 Sec R4.1.4 states that the effective fluid pressure shall be increased or decreased due to the effects of vertical acceleration, but it doesn't clearly specify under which vertical seismic direction it should be increased or decreased.
For instance, if I am considering a vertical...
I am looking for advice on designing Liquid Containing Concrete Tank with Concrete Frame on Top using American Codes-- especially the design of the concrete frame.
The project location being in a high seismic zone, I would need special seismic detailing for the concrete frame, where typically I...
I am analyzing a rectangular mat foundation using plate elements supported by springs.
Only the Soil Bearing Capacity is given in the geotechnical report, thus, I am using a subgrade modulus derived on the SBC value times FS (3) all over the allowable settlement (25mm).
After the analysis, I've...
I am investigating a column base plate anchored on top of a concrete pedestal using American Codes. I have an applied factored shear load which, unfortunately, exceeds the shear breakout capacity of the anchorage.
According to ACI 318-14, reinforcements within the lesser of 0.5ca1 and 0.3ca2...
Figure 27.3-8 of ASCE SEI 7-16 (p. 283) shows design wind load cases for Main Wind Force Resisting System of a building for all heights.
I was wondering if this load case is also applicable in designing components and cladding?
I am having a hard time figuring out the load cases I needed to...
I am designing an aluminum corner mullion for a curtain wall system.
Conventional analysis for a typical wall mullion is to have two load combinations: Case 1: Positive (towards the wall) and Case 2: Negative (away from the wall) wind load
and check the stress and deflection for both cases...
