push over analysislangkah awal :1. Assign tulangan balok kolom di section properties : define - frame section - pilih elemen - modify /show properties - reinforcement2. Run struktur3. Check and design concrete structures - pastikan semua oke4. Assign sendi plastis - untuk semua balok induk kecuali balok SW and balok pendek - 0.03M3 dan 0.95 M3 - semua kolom (kolom biasadan SW 0.05 PMM dan 0.95PMM)- select - by frame section - pilih elemen- assign - frame line - frame non linier hingesPush over1. pilih joint/titik yang akan dicek (titik tengah roof floor) - tulis nama pointnya2. definisikan pushover casesdefine - static nonlinier pushover cases - buat minimal 3 cases (a,b,c)push over cases :a. grav (load pattern : 1 DL 1 SIDL 0.25 LL)pilih : load to level defined by patternb. Push - xload : mode x dominan (1 atau 2) scale factor = 1pilih : push to display magnitude - tentukan displacementnyamonitor ux - no point - roof floorstart previous case - gravc push yload : mode y dominan, scale factor = 1pilih : push to display magnotude - tentukan dislacementmonitor : uy - no point - roof floorstart from previous case - grav3. analyze - run static non linier analysisoutput - dianalisis hasilnya1. capacity spectrum (display - show static pushover curve)Ca = Sds/2.5, Cv = Sd12. drift ratio - performance point - mance level3. R, Cd, omega o aktual4. mekanisme plastifikasi struktur
