Beating is a periodic, resonating and prolonged vibrational behavior caused by distinctive close coupling of translational and torsional modes of a lightly damped structure. Repetitively stored potential energy during the coupled translational and torsional deformations turns into repetitive vibrational energy causing the ensuing prolonged motions. Beating, if a dominant response characteristic, may impact the instantaneous and long-term shaking performances of the buildings during earthquakes. In many cases, it is noted that resonance caused by site effects also contributes to accentuating the beating effect. Records from the buildings exhibit structural responses with beating effects. Spectral analyses and system identification techniques are used to quantify dynamic characteristics used in computing beating periods. The beat frequency generally known in acoustical physics is denoted by the absolute value of the differences in frequencies that cause the phenomenon. Engineering implications of the beating may be summarized as (a) prolonged cyclic shaking due to beating effect may take its toll on the structural system, (b) repetitive shaking can accentuate fatigue and low-cycle fatigue, and (c) resonating beating cycles can and do cause discomfort to occupants. Identification of beating effects is the key to find remedial action in modification of dynamic characteristics in order to attenuate or eliminate such effects.", "publisher": { "@type": "Organization", "name": "ASCE Library" }, "author": [ { "@type": "Person", "name": "\u00c7elebi, Mehmet celebi@usgs.gov", "givenName": "Mehmet", "familyName": "\u00c7elebi", "email": "celebi@usgs.gov", "identifier": { "@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-4769-7357", "url": "https://orcid.org/0000-0002-4769-7357" } } ], "funder": [ { "@type": "Organization", "name": "Earthquake Science Center", "url": "https://www.usgs.gov/centers/earthquake-science-center" } ] }, "OpenAlex": { "abstract_inverted_index": { "Beating": [ 0, 14 ], "effects": [ 1, 89, 196 ], "observed": [ 2 ], "in": [ 3, 11, 120, 129, 141, 204, 209 ], "the": [ 4, 43, 55, 67, 74, 94, 99, 135, 139, 145, 150, 169, 198 ], "recorded": [ 5 ], "responses": [ 6, 103 ], "of": [ 7, 28, 33, 73, 138, 149, 194, 206 ], "buildings": [ 8, 75, 100 ], "are": [ 9, 113 ], "examined": [ 10 ], "this": [ 12 ], "paper.": [ 13 ], "is": [ 15, 82, 132, 197 ], "a": [ 16, 34, 61 ], "periodic,": [ 17 ], "resonating": [ 18, 183 ], "and": [ 19, 30, 46, 69, 109, 178, 181, 187 ], "prolonged": [ 20, 57, 157 ], "vibrational": [ 21, 52 ], "behavior": [ 22 ], "caused": [ 23, 86 ], "by": [ 24, 87, 134 ], "distinctive": [ 25 ], "close": [ 26 ], "coupling": [ 27 ], "translational": [ 29, 45 ], "torsional": [ 31, 47 ], "modes": [ 32 ], "lightly": [ 35 ], "damped": [ 36 ], "structure.": [ 37 ], "Repetitively": [ 38 ], "stored": [ 39 ], "potential": [ 40 ], "energy": [ 41, 53 ], "during": [ 42, 76 ], "coupled": [ 44 ], "deformations": [ 48 ], "turns": [ 49 ], "into": [ 50 ], "repetitive": [ 51, 173 ], "causing": [ 54 ], "ensuing": [ 56 ], "motions.": [ 58 ], "Beating,": [ 59 ], "if": [ 60 ], "dominant": [ 62 ], "response": [ 63 ], "characteristic,": [ 64 ], "may": [ 65, 152, 164 ], "impact": [ 66 ], "instantaneous": [ 68 ], "long-term": [ 70 ], "shaking": [ 71, 159, 174 ], "performances": [ 72 ], "earthquakes.": [ 77 ], "In": [ 78 ], "many": [ 79 ], "cases,": [ 80 ], "it": [ 81 ], "noted": [ 83 ], "that": [ 84, 143 ], "resonance": [ 85 ], "site": [ 88 ], "also": [ 90 ], "contributes": [ 91 ], "to": [ 92, 115, 161, 191, 200, 211 ], "accentuating": [ 93 ], "beating": [ 95, 105, 122, 151, 162, 184, 195 ], "effect.": [ 96 ], "Records": [ 97 ], "from": [ 98 ], "exhibit": [ 101 ], "structural": [ 102, 170 ], "with": [ 104 ], "effects.": [ 106, 216 ], "Spectral": [ 107 ], "analyses": [ 108 ], "system": [ 110 ], "identification": [ 111 ], "techniques": [ 112 ], "used": [ 114, 119 ], "quantify": [ 116 ], "dynamic": [ 117, 207 ], "characteristics": [ 118, 208 ], "computing": [ 121 ], "periods.": [ 123 ], "The": [ 124 ], "beat": [ 125 ], "frequency": [ 126 ], "generally": [ 127 ], "known": [ 128 ], "acoustical": [ 130 ], "physics": [ 131 ], "denoted": [ 133 ], "absolute": [ 136 ], "value": [ 137 ], "differences": [ 140 ], "frequencies": [ 142 ], "cause": [ 144, 189 ], "phenomenon.": [ 146 ], "Engineering": [ 147 ], "implications": [ 148 ], "be": [ 153 ], "summarized": [ 154 ], "as": [ 155 ], "(a)": [ 156 ], "cyclic": [ 158 ], "due": [ 160 ], "effect": [ 163 ], "take": [ 165 ], "its": [ 166 ], "toll": [ 167 ], "on": [ 168 ], "system,": [ 171 ], "(b)": [ 172 ], "can": [ 175, 186 ], "accentuate": [ 176 ], "fatigue": [ 177 ], "low-cycle": [ 179 ], "fatigue,": [ 180 ], "(c)": [ 182 ], "cycles": [ 185 ], "do": [ 188 ], "discomfort": [ 190 ], "occupants.": [ 192 ], "Identification": [ 193 ], "key": [ 199 ], "find": [ 201 ], "remedial": [ 202 ], "action": [ 203 ], "modification": [ 205 ], "order": [ 210 ], "attenuate": [ 212 ], "or": [ 213 ], "eliminate": [ 214 ], "such": [ 215 ] }, "apc_list": null, "apc_paid": null, "authorships": [ { "author_position": "first", "author": { "id": "https://openalex.org/A5087779431", "display_name": "Mehmet \u00c7elebi", "orcid": "https://orcid.org/0000-0002-4769-7357" }, "institutions": [ { "id": "https://openalex.org/I4210099336", "display_name": "Menlo School", "ror": "https://ror.org/01240pn49", "country_code": "US", "type": "education", "lineage": [ "https://openalex.org/I4210099336" ] } ], "countries": [ "US" ], "is_corresponding": true, "raw_author_name": "Mehmet \u00c7elebi", "raw_affiliation_strings": [ "USGS (MS977), 345 Middlefield Rd., Menlo Park, CA.
