TS EN 15129: 2018 Clause 5 - Cov khoom siv sib txuas tsis zoo rau kev nyab xeeb seismic
TS EN 15129: 2018 Clause 5 yog tus qauv tseem ceeb nyob sab Europe tswj cov khoom siv sib txuas tsis sib xws-cov khoom tseem ceeb uas txwv cov qauv kev hloov pauv thaum txhawb nqaseismic tiv thaiv systems. Tsom ntsoov rau kev ntseeg siab, kev sib raug zoo, thiab kev ua tau zoo, cov lus no tau faib cov khoom siv rau hauv peb hom kev ua haujlwm, qhia meej txog cov kev xav tau ntawm cov ntaub ntawv, tsim, thiab kev sim.
Core Scope thiab Ntaus Hom
Rigid kev twb kev txuas pab kiag li lawm txwv cov txheeb ze txav nyob rau hauv ib los yog ntau tshaj cov lus qhia, nrog tsawg kawg nkaus kab rov tav distortion. Cable txwv tsis suav nrog, thiab cov ntsiab lus ntxiv yog nyob rau hauv Annex C. Peb yam khoom tseem ceeb yog:
1. Cov khoom siv txuas mus tas li (PCD)
PCDs txwv txoj kab rov tav txhais lus (ib qho kev taw qhia rau hom txav tau, ob qho tib si rau kev ruaj khov) thaum tso cai rau kev txav ntsug thiab tag nrho kev sib hloov. Lawv tsis xa cov loads ntsug los yog dabtsi yog khoov lub sijhawm, thiab lawv tsis hloov cov txheej txheem ntuj tsim los yog lub zog tawg. Tsim los rau EN 1337-8, PCDs cia siab rau cov qauv bearings thiab ua raws li Eurocode load ua ke cov cai (EN 1337-1: 2000 Annex B). Cov ntawv thov feem ntau suav nrogchoj bearingsthiab industrial steel qauv kev sib txuas.
2. Fuse Restraints (FR)
Kuj hu ua sacrificial restraints, FRs ua raws li nruj connectors nyob rau hauv kev pab cuam loads tab sis tso mam li nco dheev thaum preset so-tawm quab yuam yog tshaj. Qhov no hloov cov qauv los ntawm kev pabcuam mus rau hom seismic, ua haujlwmKev rho tawm / damping systemsua haujlwm. FRs yog mechanical (MFR) lossis hydraulic (HFR), nrog cov ntaub ntawv ua raws li EN ISO 898 (fasteners) thiab EN 1090-2 (welding). Cov kev ntsuam xyuas muaj xws li kev pabcuam thauj khoom caij tsheb kauj vab, 2 lab rov ua dua lub voj voog (yog tias xav tau), thiab kev pov thawj kev quab yuam tawm (± 15% kam rau ua yog tias tsis tau qhia).
3. Cov khoom siv txuas ib ntus (TCD/STU)
Paub liShock Transmission Units (STUs), TCDs nthuav tawm tshaj tawm - tus cwj pwm rhiab heev: cov tshuaj tiv thaiv qis (<10% of design force) for slow thermal movements, and rigid force transmission above 0.5–5 mm/s activation velocity. They feature spherical hinges (≥±2° rotation) and minimum strokes (±50 mm for bridges, ±25 mm for buildings). Materials include ferrous alloys (EN 10025/10088) and non-toxic silicone-based fluids. Testing covers pressure resistance, seal wear (10,000 cycles), impulsive loads, and cyclic seismic simulation.
Kev Ua Raws Cai
Ua raws li Cov Cai 5 ua kom cov cuab yeej sib txuas ua ke nrog cov tshuab seismic, txhim kho cov qauv kev nyab xeeb.
Cov kab lus no muab ib qho kev sib koom ua ke rau kev txhim khu kev qha, cov cai- ua raws kev sib txuas nruj heev- qhov tseem ceeb rauav qeeg-cov vaj tse zoo, txuas hniav, thiab cov qauv kev lag luam.
