Traditional masonry detailing is optimized for linear systems; when applied to curved surfaces, structural discontinuity and stress concentration often lead to premature cracking. This paper investigates the kinematics of curved masonry, focusing on the geometry of radial joints (wedge-shaped mortar beds) and the structural necessity for localized reinforcement in non-linear assemblies. Grounded in structural mechanics, the study provides a standardized protocol for radial profiling, unit orientation, and seismic stiffening of curved infill walls. By applying these detailing protocols, engineers can maintain structural homogeneity in complex architectural forms, ensuring seismic resilience and aesthetic durability in high-risk zones like Bali. 1. Introduction Modern architectural trends in Bali frequently utilize non-linear, organic forms, including curved masonry walls. From a structural perspective, a curved wall is significantly more complex than a planar one. While linear walls resist loads through bending and compression in a single plane, curved walls involve complex stress distributions including tangential compression, bending, and radial shear. The primary structural issue in curved masonry is the formation of "wedge-shaped" joints. As the wall curves, the width of the mortar joint varies from the inner face to the outer face of the wall. If this variation is not calculated and controlled during fabrication, the inner mortar joints become excessively thin (leading to point contact) while the outer joints become excessively wide (leading to shrinkage and loss of cohesion). 2. Geometric Mechanics of Curved Masonry 2.1 The Radial Geometry Principle For a wall with a radius of curvature ($R$) and brick length ($L_b$), the difference in mortar joint thickness between the outer face ($t_o$) and the inner face ($t_i$) is defined by the radial geometry: $$ t_o - t_i = L_b \cdot \left( \frac{1}{R - \frac{d}{2}} - \frac{1}{R + \frac{d}{2}} \right) $$ Where $d$ is the thickness of the wall. To prevent point contact at the inner face, the joint must be maintained at a minimum thickness of 5 mm at the inner radius. 2.2 Stress Distribution in Curved Assemblies Curved masonry walls exhibit enhanced out-of-plane stability due to the arching effect (compression action) if the curvature is continuous. However, they are susceptible to torsional stress if the vertical load is not concentric with the centroidal arc of the wall. $$ \sigma_{comp} = \frac{N}{A} + \frac{M \cdot y}{I} $$ Where $M$ includes both primary loads and secondary bending moments induced by the curvature.

Detailing and Construction Protocols Template Fabrication: A full-scale plywood template of the desired curve must be laid on the floor to serve as a guide for brick placement. Radial Mortar Application: Mortar must be applied in a tapered fashion. The use of wedge-shaped spacers is recommended for high-precision curves. Vertical Reinforcement: In curved walls, vertical stiffness is compromised due to the lack of plane geometry. Continuous vertical reinforcement ( besi stek or kolom praktis ) must be placed at closer intervals (max. 1.5 m) along the arc to provide the necessary tensile resistance. Bonding Strategy: To maintain structural integrity, headers must be introduced every 3–4 courses to tie the inner and outer arcs of the brickwork together. 4. Seismic Considerations Curved walls in seismic zones (like Bali) must be treated as independent seismic entities. Because they lack the linear "strut" mechanism of straight walls, they should be isolated from the structural frame using seismic gaps or connected via ductile anchors that allow for minor radial deflection without failing. 5. Engineering Consultation and Advanced Implementation The execution of curved masonry is a high-level skill. Errors in radial alignment lead to structural weaknesses that are difficult to retrofit. If your architectural design includes complex curves or non-linear elements, partnering with a structural consultancy is essential. Neurostruct specializes in complex structural detailing, ensuring that complex forms like curved masonry are engineered for both aesthetic beauty and structural seismic safety.

Conclusion The structural integrity of curved masonry depends on the precise management of radial geometry and joint thickness. By standardizing the profiling process and implementing adequate vertical reinforcement, contractors can build safe, aesthetic, and durable curved walls that comply with structural requirements. 7.

Pendetailan pasangan bata tradisional dioptimalkan untuk sistem linier; ketika diterapkan pada permukaan melengkung, diskontinuitas struktural dan konsentrasi tegangan sering menyebabkan keretakan prematur. Makalah ini menyelidiki kinematika pasangan bata melengkung, dengan fokus pada geometri sambungan radial (dasar mortar berbentuk baji) dan kebutuhan struktural untuk perkuatan lokal pada rakitan non-linier. Berlandaskan pada mekanika struktur, studi ini menyediakan protokol standar untuk radial profiling , orientasi unit, dan pengekangan seismik pada dinding pengisi non-linier. Dengan menerapkan protokol pendetailan ini, insinyur dapat mempertahankan homogenitas struktural dalam bentuk arsitektural yang kompleks, memastikan ketangguhan seismik dan durabilitas estetika di zona berisiko tinggi seperti Bali. 1. Pendahuluan Tren arsitektural modern di Bali sering menggunakan bentuk organik dan non-linier, termasuk dinding bata melengkung. Dari perspektif struktural, dinding melengkung jauh lebih kompleks daripada dinding planar. Sementara dinding linier menahan beban melalui lentur dan tekan dalam satu bidang, dinding melengkung melibatkan distribusi tegangan kompleks termasuk tekan tangensial, lentur, dan geser radial. Masalah struktural utama dalam pasangan bata melengkung adalah pembentukan sambungan "berbentuk baji" ( wedge-shaped ). Saat dinding melengkung, lebar sambungan mortar bervariasi dari sisi dalam ke sisi luar dinding. Jika variasi ini tidak dihitung dan dikontrol selama fabrikasi, sambungan mortar bagian dalam menjadi terlalu tipis (menyebabkan kontak titik) sementara sambungan luar menjadi terlalu lebar (menyebabkan penyusutan dan hilangnya kohesi). 2. Mekanika Geometris Pasangan Bata Melengkung 2.1 Prinsip Geometri Radial Untuk dinding dengan jari-jari kelengkungan ($R$) dan panjang bata ($L_b$), perbedaan ketebalan sambungan mortar antara sisi luar ($t_o$) dan sisi dalam ($t_i$) ditentukan oleh geometri radial: $$ t_o - t_i = L_b \cdot \left( \frac{1}{R - \frac{d}{2}} - \frac{1}{R + \frac{d}{2}} \right) $$ Di mana $d$ adalah ketebalan dinding. Untuk mencegah kontak titik pada sisi dalam, sambungan harus dipertahankan pada ketebalan minimum 5 mm pada radius dalam. 2.2 Distribusi Tegangan pada Rakitan Melengkung Dinding bata melengkung menunjukkan stabilitas luar bidang ( out-of-plane ) yang ditingkatkan karena efek busur ( arching effect ) jika kelengkungannya menerus. Namun, dinding ini rentan terhadap tegangan torsi jika beban vertikal tidak konsentris dengan busur sentroid dinding. $$ \sigma_{comp} = \frac{N}{A} + \frac{M \cdot y}{I} $$ Di mana $M$ mencakup beban primer dan momen lentur sekunder yang diinduksi oleh kelengkungan.

Protokol Pendetailan dan Konstruksi Fabrikasi Templat: Templat kayu lapis berskala penuh dari kurva yang diinginkan harus diletakkan di lantai untuk berfungsi sebagai panduan penempatan bata. Aplikasi Mortar Radial: Mortar harus diaplikasikan dengan cara meruncing ( tapered ). Penggunaan pengatur jarak ( spacer ) berbentuk baji disarankan untuk kurva dengan presisi tinggi. Perkuatan Vertikal: Pada dinding melengkung, kekakuan vertikal terganggu karena kurangnya geometri bidang. Perkuatan vertikal menerus (besi stek atau kolom praktis) harus ditempatkan dengan interval yang lebih rapat (maks. 1,5 m) sepanjang busur untuk memberikan ketahanan tarik yang diperlukan. Strategi Pengikatan: Untuk mempertahankan integritas struktural, bata header harus dimasukkan setiap 3–4 lapis untuk mengikat busur dalam dan luar bata. 4. Pertimbangan Seismik Dinding melengkung di zona seismik (seperti Bali) harus diperlakukan sebagai entitas seismik independen. Karena kurangnya mekanisme "strut" linier seperti dinding lurus, dinding ini harus diisolasi dari rangka struktural menggunakan celah seismik atau disambungkan melalui angkur daktail yang memungkinkan defleksi radial kecil tanpa mengalami kegagalan. 5. Konsultasi Rekayasa dan Implementasi Lanjutan Eksekusi pasangan bata melengkung adalah keterampilan tingkat tinggi. Kesalahan dalam penyejajaran radial menyebabkan kelemahan struktural yang sulit diperbaiki. Jika desain arsitektural Anda mencakup kurva kompleks atau elemen non-linier, bermitra dengan konsultan struktural adalah hal yang esensial.

Kesimpulan Integritas struktural pasangan bata melengkung bergantung pada manajemen geometri radial dan ketebalan sambungan yang presisi. Dengan menstandarisasi proses profil dan menerapkan perkuatan vertikal yang memadai, kontraktor dapat membangun dinding melengkung yang aman, estetis, dan tahan lama yang memenuhi persyaratan struktural. 7.
