Inverted Pendulum Structure in AS 1170.4
Inverted Pendulum Structure in AS 1170.4
(OP)
Australian Standard AS 1170.4 (Earthquake Actions) gives an [Sp/u] factor of 0.38 for 'other steel/concrete structures'. This is the equal largest [Sp/u] for both steel and concrete. Table 6.5A.
It also gives [Sp/u] = 0.50 for 'inverted pendulum-type structures' in Table 6.5B which appears to be regardless of construction material.
Would the type of structure shown below be classed as an inverted pendulum (for the connection types shown in the elevation)? I believe each individual pile acts as an inverted pendulum but there are several of them tied together. Ie does inverted pendulum mean a single, isolated supporting element?
