The sway frame<br \/>\nbuilding is a popular structural option where such buildings are<br \/>\nrequired up to 15 or 20 storeys. In a sway frame building, the<br \/>\nrigidity of the connections between the columns and the beams or<br \/>\nslabs usually suffices to provide lateral resistance. As the 20<br \/>\nstorey height is approached, the rigidity of sway frame buildings<br \/>\ncan be insufficient and the sway due to wind may be unacceptable to<br \/>\nthe occupants of the building. In this situation, the introduction<br \/>\nof shear walls interacting with the frame may increase the total<br \/>\nrigidity, or the designer may choose another structural system,<br \/>\nwith frame-tube type buildings, shear buildings and core buildings<br \/>\nbeing the most common structures.<\/p>\n<p>For the calculation, by the modal superposition technique, of<br \/>\nthe response of a building to a fluctuating load induced by wind,<br \/>\nearthquake or mechanical vibration, a knowledge of the free<br \/>\nvibration characteristics is required. This Item provides a means<br \/>\nof estimating the free vibration characteristics of rectangular<br \/>\nsway frame buildings for use in these response calculations. In<br \/>\naddition, a method of analysis is presented enabling the free<br \/>\nvibration characteristics of more complex frame structures such as<br \/>\nlattice towers, cranes and bridges to be computed efficiently. The<br \/>\nway in which these data are used in the response of a building or<br \/>\nstructure under the action of a fluctuating wind load is described<br \/>\nin ESDU 87035 and 88019. This Item is intended to complement ESDU<br \/>\n79005, for the undamped natural vibration of shear buildings, and<br \/>\nESDU 81036, for the undamped natural vibration of core<br \/>\nbuildings.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Undamped Natural Vibration of Rectangular Sway Frame Buildings and Frame Structures<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/esdu\/\"><b>ESDU<\/b><\/a><\/td>\n<td>2011-02<\/td>\n<td>85<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":558439,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2675],"product_tag":[],"class_list":{"0":"post-558433","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-esdu","8":"first","9":"instock","10":"sold-individually","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/558433","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/558439"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=558433"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=558433"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=558433"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
