$a_{\mathrm{o}} / g=600 f_{\mathrm{r}} / W$

• $\begin{aligned} W & =\text { total weight of floors plus contents over the span } \\ & \text { length and equivalent floor width }(b), \text { in } \mathrm{N} ;\end{aligned}$
• $\begin{aligned} b & =40 t_{\mathrm{s}}(20 t_{\mathrm{s}} \text { when overhang is only on one } \\ & \text { side of the beam });\end{aligned}$
• $\begin{aligned} t_{s} & =\text { equivalent thickness of the slab, averagin } \\ & \text { concrete in slab and ribs; and }\end{aligned}$
• g = acceleration due to gravity
