“…The 3D realistic interaction between the concrete and steel has been modeled in order to reproduce the real mechanical interaction of the materials in the embossments. A similar modeling approach has been adopted in other researches [35,36]. This approach is gaining more interest from researchers due to the computation improvements of the last decades.…”

“…In the re-entrant case, since the concrete is clamped vertically -due to the shape of the profile -the ramp effect does not lead to whole interface detachment. In the FE approach developed in this study, the 3D geometrical contact of materials has been simulated to reproduce the mechanical interaction of concrete and steel, similarly adopted by [4] [25] [26]. An elastic-perfectly plastic stress-strain behavior with SHELL281 element type in Ansys element reference [27] was considered for the sheeting.…”

Composite slabs with profiled steel sheeting and cast‐in‐place concrete are a conventional structural flooring system worldwide. The partial connection method (PCM) is a design method limited to slabs showing a ductile longitudinal shear failure. The ductility is defined in Eurocode‐4 in terms of additional strength after certain initial slip is produced, regardless of the steel sheet profiling shape. This article shows that the slip behavior is significantly different depending on the shape of the sheeting profile. On the one hand, the slip magnitude in reentrant slabs can be large enough to drive the two materials to their yielding stresses; on the other hand, in open‐rib profiles, the slab failure is due to the vertical release of the concrete, when the slip overpasses certain geometric limit. This failure mode is generally produced much before the materials reaches their yielding stresses. This finding is consistent with both the experimental and FEM results carried out in this study.

“…Dalam hal ini floor deck dapat menggantikan peran bekisting pada pelat lantai [2]. Pada pelaksanaannya penggunaan wiremesh dilakukan untuk mencegah rangkak dan susut beton pada proses pengeringan [3]. Desain dari lembaran pelat floor deck ini terdapat beberapa tonjolan berpola yang berhubungan langsung dengan beton.…”

Penggunaan lembaran baja gelombang atau yang disebut dengan floor deck dalam dunia konstruksi berkembang dengan pesat. Salah satu kelebihan yang dimiliki floor deck selain bahan yang ringan dan metode kerja yang mudah adalah adanya embossment atau profil yang timbul pada permukaan floor deck hal ini bertujuan untuk mengurangi slip yang terjadi antara beton dengan floor deck. Pada penelitian ini bertujuan untuk mengetahui lendutan, regangan dan slip yang terjadi pada beton komposit akibat pembebanan statis. Benda uji yang digunakan dalam penelitian ini berjumlah 3 buah model pelat lantai dengan ukuran 1800 x 500 x 120 mm dengan mutu beton K-300 serta menggunakan floor deck setebal 0,75 mm berjenis floor deck dengan nama Di Deck. Pengujian dilakukan dengan skema pembebanan three point loads dengan kapasitas alat 100 KN. Deteksi respon akibat beban dalam pengujian menggunakan potensiometer sebagai pendeteksi defleksi yang terjadi dan strain gauge digunakan untuk mendeteksi regangan yang terjadi pada beton, steel deck dan wiremesh. Analisis yang dilakukan berdasarkan metode American Standard Institute/Steel Deck Institute C-2017. Hasil pengujian menunjukan bahwa lendutan maksimum yang terjadi sebesar 35 mm dengan slip maksimal mencapai 24,64 mm. Regangan yang terjadi maksimum terjadi pada tengah bentang untuk regangan beton mencapai 44,3 mikron.
