A 240 mm thick unreinforced sintered common brick wall ($h = 240\text{ mm}$) in a multi-story residential building has a clear story height $H = 3.3\text{ m}$. The floor and roof structural scheme is classified as a Rigid Scheme (刚性方案), for which the wall calculation height is $H_0 = 1.0 H = 3.3\text{ m}$. What is the calculated wall slenderness / height-to-thickness ratio $\beta$ (高厚比)?
