Author: Edi Supriyanto Email: edisupriyanto@gmail.com WhatsApp: https://wa.me/6281338718071/ Website: https://neurostruct.id/ Abstract The expansion of vertical residential architecture in Bali, characterized by the prevalence of two-story structures, necessitates a rigorous re-evaluation of traditional stone masonry foundation dimensions. Unlike single-story units, two-story structures impose significantly higher vertical and lateral seismic loads, rendering empirical "rule-of-thumb" sizing methodologies insufficient. This paper establishes a standardized dimensional protocol for stone masonry foundations supporting two-story residential infrastructure in volcanic soil strata. We analyze load-bearing mechanics, soil-structure interaction, and safety factors, proposing a geometry framework that minimizes differential settlement and optimizes structural load distribution. 1. Introduction The transition from single-story to two-story residential construction in Bali’s urban and semi-urban landscapes has created a structural gap in traditional building practices. Stone masonry foundations, while economical, require precise dimensional engineering to accommodate the increased dead load (from the upper floor slab, beams, and columns) and live load of two-story occupancy. Inadequate foundation geometry leads to structural distress, manifesting as wall cracking, slab depression, and diminished seismic resilience. This research provides a technical baseline for engineers and contractors to standardize foundation sizing based on load-path analysis rather than traditional estimation. 2. Theoretical Framework and Structural Load Modeling The structural sizing of the foundation is primarily determined by the total service load ($P_{total}$) transmitted to the foundation base. For a two-story residence, the load is defined as: $$P_{total} = (P_{dead} + P_{live}) \cdot L_{trib}$$ Where: $P_{dead}$ = Dead load including slab, beams, masonry walls, and roofing ($kN/m^2$). $P_{live}$ = Occupancy load as per standard codes ($kN/m^2$). $L_{trib}$ = Tributary width of the floor area supported by the foundation wall ($m$). The foundation width ($B$) must ensure that the pressure on the subgrade ($q$) does not exceed the allowable bearing capacity ($q_{all}$): $$B \geq \frac{P_{total}}{q_{all}}$$ For two-story structures in Bali, where $q_{all}$ for volcanic strata typically ranges from $120-180 kN/m^2$, the base width $B$ is generally required to be between $0.8m$ and $1.0m$. Furthermore, the depth of the foundation ($D$) must extend below the active soil zone, typically $\geq 0.8m$, to avoid moisture-induced volume changes in the tropical climate. 3. Methodology: The Neurostruct Two-Story Protocol To ensure structural integrity, our standardized protocol mandates the following specifications: Load Path Audit: Calculating the exact total gravity load of the two-story superstructure before determining foundation dimensions. Dimensional Standardization: Base Width ($B$): Minimum $0.8m - 1.0m$. Top Width ($T$): Minimum $0.4m$ to accommodate the reinforced concrete tie beam ( sloof ). Depth ($D$): Minimum $0.8m$ to $1.0m$ to ensure deep soil bearing capacity. Lateral Stability: Implementing a trapezoidal profile to enhance load distribution and seismic energy absorption. Subgrade Preparation: Compacting a 150mm granular base layer to distribute load uniformity across the soil contact surface. 4. Discussion: Engineering Resilience Field verification confirms that adhering to these standardized dimensions for two-story buildings significantly reduces the frequency of tension cracks in load-bearing walls. By increasing the base width $B$, we decrease the contact pressure on the soil, thereby staying well within the elastic limits of the underlying volcanic strata. This prevents the "tipping" or "tilting" movements that often characterize sub-dimensioned foundations under lateral seismic excitation. 5. Engineering Recommendations For two-story construction, foundation design is a critical structural decision that cannot be simplified. We strongly recommend professional structural engineering oversight for all multi-story projects. Engage Neurostruct for structural load-path analysis, foundation dimension certification, and construction site supervision.

Mengapa Rumah 2 Lantai Butuh Pondasi yang Lebih Kuat? Membangun rumah 2 lantai berbeda jauh dengan rumah 1 lantai. Beban yang ditopang pondasi dua kali lipat lebih berat—mulai dari lantai atas, balok, kolom, hingga dinding lantai dua. Kesalahan fatal banyak kontraktor di Bali adalah menyamakan dimensi pondasi rumah 2 lantai dengan rumah 1 lantai. Jika pondasinya "kekecilan" (under-dimensioned), rumah Anda akan mengalami penurunan tidak merata ( differential settlement ) yang berujung pada retak struktur di seluruh dinding. Jangan biarkan investasi rumah Anda rusak karena pondasi yang tidak kompeten! Rumus Teknik: Rahasia Menghitung Pondasi yang Aman Di Neurostruct , kami tidak bekerja dengan "feeling". Kami menghitung total beban bangunan ($P_{total}$) agar pondasi Anda aman selamanya. Kami menggunakan prinsip dasar teknik sipil untuk menentukan lebar pondasi ($B$): $$B \geq \frac{P_{total}}{q_{all}}$$ Untuk rumah 2 lantai di Bali, kami biasanya menyarankan dimensi pondasi batu kali dengan lebar bawah (base) minimal 80 cm hingga 100 cm dan lebar atas minimal 40 cm . Ini adalah batas aman agar tanah mampu menopang beban rumah Anda tanpa ambles, bahkan saat terjadi guncangan seismik. Solusi Neurostruct: Pondasi Kelas Resort untuk Bangunan 2 Lantai Kami membawa standar engineering tinggi agar rumah 2 lantai Anda kokoh: Audit Beban: Kami menghitung total beban struktur untuk memastikan pondasi Anda memiliki dimensi yang tepat, tidak terlalu boros tapi sangat aman. Stabilitas Geometri: Desain trapesium yang tepat untuk distribusi beban yang sempurna. Pematangan Struktur: Teknik pasangan yang memastikan setiap batu terkunci dengan kuat.
