Hi
I have a question regarding a RC shear wall supported on Steel Piles. Please see link for shear wall and pile configuration.
When a lateral load is applied to the shear wall, there is overturning moments on the wall in addition to shear and axial loads. If we assume that all of the rebars...
I have carried out a response spectrum analysis for a reinforced concrete moment frame building and have the following questions:
a) Do you combine U1 and U2 acceleration in a single RS case?
b) My columns experience biaxial bending. With the response spectrum I have min and max values for...
Hi
When modelling boxed, C-shpaed and L-shaped shear walls in Etabs for low rise buildings, there are large tension and compression forces on the flanges when primary seismic loads are applied in the web's direction. This is because Etabs treats it as coupled wall. If these walls are concrete...
Are we permitted to use the action combination factors kc,e and kc,i from Table 5.5 of AS1170.2: 2011, when designing the Roof cladding and Purlins for internal pressure?
This is particularly for buildings designed in region C and D, which can have very large internal pressures.
Previously...
Hi
I have Reinforced Concrete frame building, where my beam's hogging moment is higher for gravity case than that for seismic case. If I undertake a ductile design in accordance with NZ seismic code (NZS1170.5), I am required to design my columns for the over strength of the beams capacity...
