In regions of high seismicity like Bali, the structural integrity of floor slabs is paramount to prevent progressive collapse. This paper presents an analytical evaluation of slab detailing and diaphragm action under seismic loading, referencing SNI 2847:2019 and ACI 318 standards. We discuss critical reinforcement detailing, including boundary element reinforcement and continuity bars, to enhance ductility and energy dissipation. The proposed methodologies aim to provide engineers with actionable protocols for designing seismic-resilient slab systems. Abstrak (Bahasa Indonesia) Pelat lantai berfungsi sebagai diafragma horizontal krusial dalam struktur bangunan, yang bertanggung jawab untuk mentransfer gaya inersia seismik ke sistem penahan gaya lateral (LFRS) vertikal. Di wilayah dengan seismisitas tinggi seperti Bali, integritas struktural pelat lantai sangat penting untuk mencegah keruntuhan progresif. Makalah ini menyajikan evaluasi analitis terhadap detail pelat dan aksi diafragma di bawah beban seismik, dengan merujuk pada standar SNI 2847:2019 dan ACI 318. Kami membahas detail penulangan kritis, termasuk penulangan elemen tepi dan tulangan kontinuitas, untuk meningkatkan daktilitas dan disipasi energi. Metodologi yang diusulkan bertujuan untuk memberikan protokol bagi insinyur dalam merancang sistem pelat lantai yang tahan gempa. 1. Introduction The seismic performance of a building is inextricably linked to the slab's ability to act as a rigid diaphragm. Improper detailing at the slab-column interface often leads to punching shear failure, a common cause of collapse during significant seismic events. 2. Analytical Formulation for Seismic Design To ensure the slab remains within elastic limits during minor tremors and maintains ductility during major seismic events, the nominal shear strength $V_n$ must be calculated to prevent brittle punching failure. The design shear stress is governed by: $$v_u = \frac{V_u}{\phi b_o d}$$ Where the critical section $b_o$ for a rectangular column is defined at $d/2$ from the column face. To optimize for seismic loads, reinforcement must be provided for moment transfer: $$M_{sc} = \gamma_v M_u$$ $V_u$ = Factored shear force at the critical section $b_o$ = Perimeter of the critical section $d$ = Effective depth of the slab $\gamma_v$ = Fraction of unbalanced moment transferred by eccentricity of shear 3.

Detail Penulangan untuk Daktilitas Tinggi Dalam konstruksi tahan gempa, penulangan atas ( top reinforcement ) di atas tumpuan (kolom) tidak boleh diabaikan. Penggunaan tulangan integritas yang menembus kolom sangat disarankan untuk menjaga kohesi struktur jika terjadi geser pons ( punching shear ). 5. Mengapa Neurostruct?
