Indonesia merupakan wilayah dengan aktivitas seismik tinggi, sehingga infrastruktur bangunan perumahan perlu dirancang andal terhadap beban gempa. Dalam praktik konstruksi, dinding pengisi sering dianggap sebagai elemen nonstruktural, padahal keberadaannya memengaruhi perilaku lateral struktur secara signifikan. Penelitian ini bertujuan untuk mengkaji respons siklik portal beton bertulang skala penuh dengan dinding pengisi panel pracetak beton ringan akibat beban lateral. Pengujian dilakukan pada bagian atas portal untuk memperoleh data hubungan beban-perpindahan, kapasitas maksimum, degradasi kekakuan, disipasi energi, EVDR, serta kronologi pola retak. Pada perbandingan akan melihat kurva histeritik, penurunan kekakuan dan EVDR dari benda uji penelitian sebelumnya. Hasil pengujian menunjukkan kapasitas kekuatan maksimum benda uji pada arah dorong sebesar 42,38 kN pada perpindahan 106,85 mm, dan pada arah tarik sebesar 46,88 kN pada perpindahan 107,35 mm. Kekakuan awal spesimen sebesar 7,627 kN/mm menurun secara bertahap hingga menyusut ke titik terendah sebesar 0,047 kN/mm pada perpindahan akhir sekitar 107,1 mm. Sementara itu, akumulasi energi disipasi maksimum mencapai 1428,603 kN·mm pada arah dorong dan 809,145 kN·mm pada arah tarik. Pola kerusakan struktural diinisiasi oleh retak pada sambungan sebelah dalam, yang berkembang menjadi retak diagonal, pemisahan bidang kontak panel-kolom, serta kerusakan lokal pada sambungan kolom - balok dan kolom - sloof. Secara umum, portal dengan dinding panel pracetak beton ringan terbukti andal dalam menahan beban lateral dan mempertahankan kapasitas struktural pada perpindahan besar.

Indonesia is a country characterized by a high level of seismic activity, which necessitates that residential buildings be designed to demonstrate robust performance against earthquake loads. In conventional engineering practice, infill walls are frequently categorized as non-structural elements; however, their presence can significantly influence the global lateral behavior of the structure. This study aims to investigate the cyclic behavior of a reinforced concrete frame infilled with precast lightweight concrete panel walls subjected to lateral loading. The experimental test specimen consisted of a full-scale reinforced concrete frame equipped with precast lightweight concrete panel infill walls. Testing was conducted by applying cyclic lateral loads to the top of the frame to acquire comprehensive data regarding the load-displacement relationship, peak capacity, stiffness degradation, energy dissipation, EVDR and the chronological progression of cracking patterns. Comparisons will examine the hysteresis curves, stiffness degradation, and EVDR from test specimens in previous studies. The experimental results indicated that the peak load capacity of the specimen in the push direction was 42.38 kN at a displacement of 106.85 mm, whereas the capacity in the pull direction reached 46.88 kN at a displacement of 107.35 mm. The initial stiffness of 7.627 kN/mm decreased to 0.047 kN/mm at a final displacement of approximately 107.1 mm, confirming a gradual stiffness degradation process. Furthermore, the maximum cumulative energy dissipation in the push direction reached 1428.603 kN·mm, while the dissipation in the pull direction reached 809.145 kN·mm. The structural damage progression initiated with cracking along the inner interface contact zone, which subsequently developed into diagonal cracks, separation of the panels from the bounding columns, and localized failure at the beam - column and column - sloof (ground beam) connections. In general, the reinforced concrete frame with precast lightweight concrete panel walls demonstrated a reliable capacity to sustain lateral loads and maintain structural integrity at large displacement levels.
