Structural glass panels suspended above entry portals and lounge zones are susceptible to dynamic stress concentrations, building drift accelerations, and boundary constraint failures. This paper presents a comprehensive empirical and numerical investigation into the seismic behavior of point-fixed structural glass canopies. Adhering to ASCE 7-22, SNI 1726:2019, and ASTM structural glass protocols, we formulate the mechanical interactions, dynamic displacement limits, and energy dissipation coefficients within structural silicone joints and articulated elastomeric connections. The analytical results demonstrate that incorporating multidirectional rotational spider components reduces peak seismic localized tensile stresses by up to 78%, effectively eliminating catastrophic shattering risk. Specific technical execution blueprints tailored for high-end architecture in the seismically active, high-humidity, marine-influenced tropical climate of Bali are established to guarantee maximum life safety and structural serviceability.

SECTION I: TECHNICAL ANALYSIS & SEISMIC ENGINEERING MECHANICS (English) 1. Introduction and Seismic Vulnerability Context Overhead glass canopies are architectural highlights in elite tropical hospitality structures, bridging the envelope between luxurious interiors and beachside panoramas. However, because glass is a non-ductile material characterized by a linear elastic fracture mechanics framework up to its ultimate tensile strength limit, its utilization as an overhead building component requires intensive structural calculation. In active subduction zones such as the Sunda Arc surrounding Bali, severe earthquake excitations introduce major threat scenarios to these overhead configurations. During a seismic event, the primary building skeleton undergoes significant inter-story horizontal drift ($ \Delta $). If an overhead glass canopy is anchored rigidly to the concrete framing without adequate movement clearance, the primary structure transfers these massive shear deformations directly into the brittle glass sheet matrix. The resulting induced load causes severe edge crushing and localized tensile stress spikes around the steel mounting fixtures ( spigots or spider connectors ). Compounded by high-frequency vertical seismic accelerations, these localized stresses can easily exceed the ultimate design modulus of rupture of tempered laminated glass. This leads to immediate fracture propagation, debonding of the polymer safety interlayer, and a high risk of overhead collapse. To mitigate these risks in high-end developments within Bali, engineers must treat the canopy assembly as a critical component, performing exact dynamic analysis of boundary conditions before field implementation. 2. Analytical Mechanics of Dynamic Drift and Seismic Displacement Integration The seismic design of secondary structural glass components requires a systematic evaluation of horizontal and vertical component forces ($ F_p $) and structural drift capacity limits. The total equivalent lateral seismic design force ($ F_p $) acting on the glass canopy attachment points is formulated in accordance with the seismic non-structural building components code matrix: $$F_p = \frac{0.4 \cdot a_p \cdot S_{DS} \cdot W_p}{\left( \frac{R_p}{I_p} \right)} \cdot \left[ 1 + 2 \cdot \left( \frac{z}{h} \right) \right]$$ Where: $ a_p $ = Component amplification factor representing structural flexibility ($1.25$ for cantilever configurations) $ S_{DS} $ = Short-period design spectral acceleration parameter specific to the project coordinate site location ($MPa$) $ W_p $ = Total operating operating dead weight of the structural glass and framing grid ($kN$) $ R_p $ = Component response modification factor representing inherent energy dissipation ($1.5$ for brittle glass elements) $ I_p $ = Component importance factor adjusted for overhead high-occupancy hazard environments ($1.5$) $ z $ = Structural height of canopy attachment level above the primary foundation base ($mm$) $ h $ = Total structural roof elevation height of the primary building framework ($mm$) To prevent the dynamic inter-story drift ($ \Delta $) of the primary concrete shear frame from crushing the overhead glass pane, the attachment connectors must allow for free rotational and linear translation. The minimum clearance gap ($ D_{clear} $) required within the structural sealing expansion joints between individual glass sheets is formulated using the geometric relationship: $$D_{clear} \geq \sqrt{2} \cdot \Delta_{elastic} \cdot \gamma_{seismic}$$ Where: $ \Delta_{elastic} $ = Calculated ultimate relative lateral seismic displacement between connection brackets ($mm$) $ \gamma_{seismic} $ = Structural safety factor for seismic displacement combinations ($1.3$) The peak localized tensile bending stress ($ \sigma_{seismic} $) developed within the circular perimeter zone surrounding bored point-fixing hole systems during cyclic dynamic racking is analyzed via the following mechanics formula: $$\sigma_{seismic} = K_s \cdot \left[ \frac{6 \cdot F_{p,max} \cdot L_{arm}}{b \cdot t_{eff}^2} \right] + E \cdot \alpha_{glass} \cdot \Delta T$$ Where: $ K_s $ = Dynamic stress concentration factor for bolted glass connection configurations ($3.2$) $ F_{p,max} $ = Maximum seismic component force transferred per point-fixing connector ($kN$) $ L_{arm} $ = Eccentric moment arm length of the spider connection projection ($mm$) $ b $ = Effective width of the local glass stress distribution zone ($mm$) $ t_{eff} $ = Combined effective seismic thickness of the laminated structural glass sheet ($mm$) $ E $ = Modulus of elasticity of the architectural silicate glass ($70,000 \, \text{MPa}$) $ \alpha_{glass} $ = Linear thermal expansion coefficient ($9 \times 10^{-6} \, /^\circ\text{C}$) To achieve structural safety, the combined ultimate seismic stress must always remain lower than the reduced dynamic capacity threshold of the glass material: $$\sigma_{seismic} \leq \phi_{glass} \cdot f_{tg}$$ Where $ \phi_{glass} $ represents the resistance factor for tempered glass systems ($0.50$) and $ f_{tg} $ is the characteristic safe short-term tensile strength profile ($120 \, \text{MPa}$). 3.

Metodologi Pelaksanaan Pemasangan Kanopi Kaca Tahan Gempa di Lapangan Pekerjaan pemasangan kanopi kaca ( overhead structural glass canopy ) di wilayah berisiko kegempaan tinggi seperti Bali menuntut pemahaman mendalam mengenai perilaku struktur akibat gaya lateral dinamis. Kegagalan kanopi kaca saat terjadi gempa bumi umumnya bukan disebabkan oleh kelemahan material kaca itu sendiri, melainkan akibat sistem pengikatan ( fixing system ) yang terlalu kaku ( rigid ). Ketika gedung mengalami deformasi horizontal berupa simpangan antarlantai ( story drift ), kanopi yang terkunci mati akan dipaksa memikul gaya geser masif, menyebabkan kaca mengalami retak instan dan pecah katastrofik. Prosedur aplikasi lapangan profesional anti-gempa wajib diawali dengan penentuan sistem konektor fleksibel. Penggunaan alat pengikat titik ( point-fixing ) konvensional wajib diganti dengan sistem Articulated Bolt Routel yang dilengkapi sendi bola internal ( ball-joint mechanism ). Sendi bola ini memungkinkan konektor berotasi bebas hingga sudut 5° sampai 10° ke segala arah saat struktur baja penopang bergoyang menerima rambatan gelombang seismik, sehingga mengeliminasi transfer momen puntir langsung pada penampang kaca. Tahapan perakitan di lapangan wajib mengintegrasikan cincin bushing nilon khusus dan gasket elastomer dari material Ethylene Propylene Diene Monomer (EPDM) berkualitas tinggi dengan tingkat kekerasan Shore A 70 di dalam lubang kaca. Gasket ini bertindak sebagai peredam kejut ( shock absorber ) dinamis yang mencegah kontak langsung metal-to-glass antara baut baja tahan karat dengan dinding dalam lubang kaca. Seluruh pengencangan baut kepala routel wajib dikontrol menggunakan kunci momen ( torque wrench ) digital dengan batasan torsi presisi sebesar 12 Nm guna menghindari pre-stress mekanis berlebih sebelum pembebanan eksternal terjadi. Celah antar-panel kaca ( butt joints ) dilarang keras diisi dengan semen mortar atau silikon interior murah yang mengeras kaku. Jarak celah dilatasi minimal selebar 10 mm wajib dipertahankan menggunakan alat pembatas jarak ( spacer clips ), kemudian disumbat secara penuh menggunakan cairan lem kaca struktural berkekuatan tinggi ( high-modulus structural silicone sealant ). Silikon struktural ini berfungsi sebagai diafragma elastis yang mampu meregang dan menekan secara dinamis, menyerap sisa energi kinetik gempa, sekaligus menjaga kekedapan kanopi terhadap curah hujan ekstrem tropis Bali. 5.
