EARTHQUAKE LOADS

1613.2 Seismic ground motion values. Seismic ground motion values shall be determined in accordance with this section. 1613.2.1 Mapped acceleration parameters. The parameters SS and S1 shall be determined from the 0.2 and 1-second spectral response accelerations shown on Figures 1613.2.1(1) through 1613.2.1(8) and Table 1613.2.1. Where S1 is less than or equal to 0.04 and SS is less than or equal to 0.15, the structure is permitted to be assigned Seismic Design Category A. 141 Quebradillas Barceloneta Cataño Aguadilla Hatillo Dorado 133 Isabela 122 119 113 125 Vega Baja 104 Manatí Vega Toa Baja 99 Loíza Rincón Camuy Arecibo 107 Alta 101 Carolina 98 119 110 116 Florida 106 Bayamón San Juan 97 Moca ToaAlta 98 98 135 Aguada 125 110 99 133 Trujillo Rio Grande Luquillo Guaynabo Alto 97 98 Culebra San Sebastián Morovis Corozal 98 96 119 Ciales 103 99 Fajardo Canóvanas Añasco 98 106 Naranjito 125 Lares Utuado 96 97 Aguas Gurabo 112 116 112 Buenas 95 Ceiba Las Marías Comerío 95 Juncos Naguabo 98 118 Jayuya Orocovis 105 101 96 Caguas 95 Las 97 Mayagüez 124 Barranquitas 94 Piedras Maricao Adjuntas Hormigueros 117 110 97 Cidra 96 94 Humacao 124 Villalba Aibonito 96 101 96 San Lorenzo 94 Vieques San Germán Coamo Cayey Sabana Yauco 102 125 97 Grande 93 Yabucoa 125 Peñuelas 125 Ponce 96 115 Cabo Rojo 107 Juana Díaz 135 Lajas Guayanilla 100 Salinas Patillas Maunabo 130 Guánica 125 Guayama 93 93 96 125 Santa Isabel 92 Arroyo 96 92 FIGURE 1613.2.1(6)A SPECTRAL RESPONSE ACCELERATION AT PERIOD OF 0.2 SECONDS, 5% OF CRITICAL DAMPING, RECURRENCE OF 2,475 YEARS (PROBABILITY OF EXCEEDANCE OF 2% IN 50 YEARS) 142 Barceloneta Cataño Aguadilla 48 Dorado 50 Isabela 43 Vega Baja 40 49 Toa Baja 39 Manatí Vega Camuy Arecibo 42 Alta 40 Carolina Loíza 39 Hatillo 43 Moca 47 45 41 San Juan 39 46 Florida 39 Rincón Aguada 49 42 ToaAlta Bayamón 39 Guaynabo 38 50 Rio Grande Luquillo Culebra Trujillo San Sebastián Morovis Corozal 39 39 39 53 Alto 47 Ciales 39 39 38 39 39 Canbuanas 38 Fajardo Añasco 40 48 Lares Utuado 40 Naranjito Aguas Gurabo 44 43 Buenas 37 38 Ceiba Las Marías Comerío 37 37 Naguabo 46 41 Orocovis Juncos Mayagüez Jayuya 37 Caguas 37 39 48 38 Maricao Adjuntas 36 36 Barranquitas 37 Hormigueros 46 43 Cidra Las Humacao Aibonito 36 Piedras 49 Villalba 36 48 39 36 San Lorenzo 47 Vieques 37 San German Coamo Cayey Sabana Yauco 43 37 Grande 46 35 Yabucoa Peñuelas Ponce 35 Cabo Rojo 46 42 Juana Díaz 53 Lajas 50 Guayanilla 38 Salinas Santa Isabel Arroyo Patillas 51 Guayama 35 34 34 Guanica 34 36 34 FIGURE 1613.2.1(6)B SPECTRAL RESPONSE ACCELERATION AT PERIOD OF 1.0 SECONDS, 5% OF CRITICAL DAMPING, RECURRENCE OF 2,475 YEARS (PROBABILITY OF EXCEEDANCE OF 2% IN 50 YEARS) 143 Table 1613.2.1 Spectral Response Accelerations for Municipalities of Puerto Rico, % of g. 0.2 1.0 0.2 1.0 0.2 1.0 MUNICIPALITIES MUNICIPALITIES MUNICIPALITIES Sec Sec Sec Sec Sec Sec ADJUNTAS 110 43 FAJARDO 98 39 NAGUABO 97 37 AGUADA 133 50 FLORIDA 110 42 NARANJITO 97 38 AGUADILLA 133 50 GUÁNICA 125 50 OROCOVIS 101 39 AGUAS BUENAS 95 37 GUAYAMA 92 34 PATILLAS 93 34 AIBONITO 96 36 GUAYANILLA 125 46 PEÑUELAS 115 43 AÑASCO 125 48 GUAYNABO 98 39 PONCE 107 42 ARECIBO 116 45 GURABO 95 37 QUEBRADILLAS 122 48 ARROYO 92 34 HATILLO 119 46 RINCÓN 135 53 BARCELONETA 113 43 HORMIGUEROS 124 49 RIO GRANDE 97 39 BARRANQUITAS 97 38 HUMACAO 96 36 SABANA GRANDE 125 47 BAYAMÓN 98 39 ISABELA 125 49 SALINAS 93 35 CABO ROJO 135 53 JAYUYA 105 41 SAN GERMÁN 125 48 CAGUAS 94 36 JUANA DÍAZ 100 38 SAN JUAN 98 39 CAMUY 119 47 JUNCOS 95 37 SAN LORENZO 94 36 CANÓVANAS 96 38 LAJAS 130 51 SAN SEBASTIÁN 119 47 CAROLINA 97 39 LARES 116 44 SANTA ISABEL 96 36 CATAÑO 99 39 LAS MARÍAS 118 46 TOA ALTA 99 39 CAYEY 93 35 LAS PIEDRAS 96 37 TOA BAJA 101 40 CEIBA 98 38 LOIZA 98 39 TRUJILLO ALTO 96 38 CIALES 106 40 LUQUILLO 98 39 UTUADO 112 43 CIDRA 94 36 MANATÍ 110 43 VEGA ALTA 106 41 COAMO 97 37 MARICAO 117 46 VEGA BAJA 107 42 COMERIO 96 37 MAUNABO 96 34 VIEQUES 102 37 COROZAL 99 39 MAYAGÜEZ 124 48 VILLALBA 101 39 CULEBRA 112 40 MOCA 125 49 YABUCOA 96 35 DORADO 104 40 MOROVIS 103 39 YAUCO 125 46 144 CHAPTER 17 - SPECIAL INSPECTIONS AND TEST
