Hi, Problem: ============================ in a low-rise (5 levels) 72.0 m x 48.0 m - RC-structure, I am considering to let plastic deformations take place in the concrete slab (diaphragm) aiming to reduce the huge forces going from the slab into the stiff vertical RC-core and RC perimeter walls. In capacity design, diaphragms are usually treated as rigid members (when compared with the stiffness of the vertical members) delivering horizontal inertia forces into the vertical members. The latter are usually designed with sufficient ductility to allow for the buildup of plastic hinges at assigned locations. In my case, however, the wide-extended slab may crack and develop plastic deformations. ================================================== Do you have experience with a similar problem or did you ever came across an article dealing with this problem? I will appreciate any advice. Thanks in anticipation, Peter Rangelow ==================================================== Deutschherrnufer 29 tel : + (49-69) 6199-1806 60594 Frankfurt am Main fax : + (49-69) 6199-1805 GERMANY rangelow(--nospam--at)dialup.nacamar.de ==================================================== --- Internet Message Header Follows --- Received: from server1.seaoc.org (bqe.com [184.108.40.206]) by host1.texramp.net (8.8.5/8.8.5) with SMTP id PAA13603 for <rlewis(--nospam--at)techteam.org>; Sun, 6 Apr 1997 15:03:05 -0500 (CDT) Received: from authsrv.nacamar.de by server1.seaoc.org (NTList 3.02.10) id pa016707; Sun, 6 Apr 1997 12:57:35 -0700 Received: from PETEL.nacamar.de ([220.127.116.11]) by dialup.nacamar.de (8.8.5/8.7.3) with SMTP id VAA10287 for <seaoc(--nospam--at)seaoc.org>; Sun, 6 Apr 1997 21:55:21 +0200 (MET DST) Message-Id: <18.104.22.16870406195522.00688d88(--nospam--at)dialup.nacamar.de> X-Sender: seaoc-ad(--nospam--at)seaoc.org X-Mailer: Windows Eudora Pro Version 2.2 (32) Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Date: Sun, 06 Apr 1997 21:55:22 +0200 To: seaoc(--nospam--at)seaoc.org From: Peter Rangelow <rangelow(--nospam--at)dialup.nacamar.de> Subject: [Q] Plastic Deformation in a diaphragm Reply-To: seaoc(--nospam--at)seaoc.org Error-To: seaoc-ad(--nospam--at)seaoc.org X-Loop: seaoc(--nospam--at)seaoc.org X-Info: [SEAOC] Owner: seaoc-ad(--nospam--at)seaoc.org X-POP3-Rcpt: seaoc-ad(--nospam--at)seaoc.org Precedence: list X-ListMember: rlewis(--nospam--at)techteam.org [seaoc(--nospam--at)seaoc.org] __________________________________________________ Richard Lewis, P.E.
