effect of sliding mod on core walls and seismic  The most important construction process of an executive you need to control is the use of sliding mold In tower buildings, high skyscrapers in high-intensity seismic zones  The full pour the concrete core and then use the dowel bolts and splices later In connecting slabs and the ceiling beams to concrete core In areas with high seismic intensity 3-4  These links will transfer full forces of to earthquakes core Without concrete intervention where is poured between the core and slab separator  These connectors are exposed and dowel from the ceiling to the core wallsTo alternating stresses and forces of shear stress and the forces of alternating tension and compression  that could lead to hinge form in the plastic connecting points And cracked (concrete) and plastic rebar or bolts connecting  Separation the ceiling slab of the core and cracked building So you must ensure adequate experience and good study and details of when in use mold sliding and connecting the ceiling later.  **With that this is contrary to the precepts and requirements of engineering codes Especially in the areas of strong earthquakes Where all the codes recommends pouring the slab with the core once Otherwise assumptions design earthquakes diaphragm rigid to change semi rigid 7

Conclusion and Results • We are not against modernizing and developing ways and mechanisms of execution equipment sliding mold And other moldings rapid formwork

• But we must find ways and designs in the event of the use the sliding mold And connecting slabs and paths the forces of earthquakes collectors to junctions walls of core So that they are buried by walls of core as seen in the previous page • must indicate expressly on the execution plans using sliding moldings With drawings and details necessary to connect later slabs and beams with walls core 27
