“…A steel header beam was installed by using a single large bolt in each panel centerline which runs parallel to the wall as depicted in Figure 14. Meanwhile, Schoettler (2010), Henry (2011) and Liu (2016) have adopted a special isolation connection which based on the commercial product. The wall-floor connections in their project were designed to permit free relative vertical movement and free relative rotation by allowing the transfer of horizontal forces from the floors to the wall.…”

“…If the precast floor is placed parallel towards the rocking wall where the floor ends is supported by a precast frame (usually at precast beam element), only lateral inertia forces will be transferred while the gravitational floor load is mainly distributed to the precast structural frame. Typically, the special isolation connection is used to transfer the inertia forces as demonstrated in Schoettler (2010), Henry (2011) and Liu (2016) project. On the other hand, the bearing orientation of precast floor towards the rocking wall will create significant gravitational floor load transfer to the rocking wall system where the floor damage is inevitable in this condition.…”

“…The numerical studies conducted by Henry demonstrated that the moment resistances of buildings with rigid wall-floor connections were much higher than those of buildings with vertical movement isolated connections. The moment demands on the floor at the wall-floor connections can be quantified as proposed by Liu (2016) = 4 + 2 − 6 −∆ = �4 + 2 + 6 � , =…”

“…Hence, the wall-to-floor connection could be designed to transfer horizontal inertia loads with unrestrained displacement in the vertical direction. In this regard, most of the precast floor are pinned connection in parallel orientation towards the rocking wall and the special isolation connection was utilized to isolate the vertical displacement of the rocking wall against the precast floor as demonstrated by Schoettler (2010), Henry (2011) and Liu (2016). Unlike the precast frame structures, predominantly, the precast concrete wall in load-bearing structures must take up all the gravity floor load rather transfer the horizontal inertia loads.…”

The severe damage of precast concrete wall structures that have been recorded in the past earthquake has led to the innovation of the rocking wall concept which can demonstrate free or minimum damage aftershock of an earthquake. Furthermore, extensive research works have been well conducted in the past three decades on the establishment of precast rocking wall systems, designs, details, and techniques. Despite this extensive development, little attention has been devoted to investigate the interaction between the rocking wall systems and the flooring diaphragm. The historical perspective on the development of rocking wall systems over the past few decades in the precast concrete structures is presented. Subsequently, the limited research works on the interaction of precast rocking wall to the floor diaphragm are described. Apart from that, this paper attempts to highlight the application of rocking wall systems in the context of precast connection for the precast load-bearing structures. In this contribution, the precast rocking wall-floor connection for precast load-bearing structures is proposed and presented in this paper.
