Masonry walls features

Post by Lauperalta97 »

Hello community,

I'm currently exploring various configurations for a prototype, incorporating masonry walls into my model to evaluate their response to lateral loads. To achieve this in Seismosoft, I must determine seventeen coefficients for the MW macro model by Crisfaulli (1997). However, lacking experimental data, I attempted to model an experiment from Stalyanidis (2012) using Seismosoft's building modeler tools.

Values for strut and shear mechanism parameters depend on factors like brick length, height, mortar thickness, mean brick and mortar compressive strengths. My questions mainly concern how Seismosoft interprets these parameters.

The strut curve parameter's first value represents the initial Young modulus (E), and the second value is the maximum compressive strength at the theta angle (fm). While I understand E = fm/1000 per Paulay and Priestly, I'm unsure how Seismosoft calculates E with the given values.

Similarly, the Shear Curve parameter's first value indicates shear bond strength (Sb), and the second value denotes maximum shear resistance (Sm), calculated as Sm = Sb * 2. I'm uncertain about the basis for this formula and how Seismosoft derives Sb.

These queries are vital for my research, requiring thorough justification of values employed by the software.

Your assistance on this matter would be greatly appreciated.

Thank you.

Hi
It's my research field too ( RC frames with masonry infill) I have many questions about the Crisafulli model ...
