After going through to many literature about damping consideration I am now confuse what damping should I consider. Can any one simple some of the questions I have.<\/p>\n<p>1) I have first three frequency of my structure along with the respective damping which 1.66 Hz\/2.40 %, 5.90Hz\/2.40% and 10.20Hz\/1.1% respectively. How I can decide what two frequency I should select and what is the criteria for the selection calculating alpha and beta for rayleigh damping?<\/p>\n<p>2) Additional, my structure is reinforced concrete so do I need to define in material data of both steel and concrete the value of alpha and beta?<\/p>\n<p>3) What damping need to be consider for full transient analysis? I.e material dependent damping or rayleigh damping or any other or a combination?<\/p>\n<p>Note: My analysis is a full tansient for an RCC structure having an earthquake loading.<\/p>\n<p><\/p>\n<\/p>\n<p>Best regard<\/p>\n","protected":false},"template":"","class_list":["post-164143","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["6774"],"_bbp_likes_count":["0"],"_bbp_subscription":["239140"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["164143"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","199977"],"_bbp_voice_count":["2"],"_bbp_reply_count":["17"],"_bbp_last_reply_id":["198222"],"_bbp_last_active_id":["198222"],"_bbp_last_active_time":["2021-11-23 12:06:41"]},"test":"mereenhussainbalochgmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/164143","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/164143\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=164143"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
