規範條文...(大家正經一點~!) - 土木

找了一下原文 ACI318-05

9.3.4節

(a) For any structural member that is designed to
resist E, φ for shear shall be 0.60 if the nominal
shear strength of the member is less than the shear
corresponding to the development of the nominal
flexural strength of the member. The nominal flexural
strength shall be determined considering the
most critical factored axial loads and including E;

R9.3.4

Section 9.3.4(a) refers to brittle members such as low-rise
walls, portions of walls between openings, or diaphragms
that are impractical to reinforce to raise their nominal shear
strength above nominal flexural strength for the pertinent
loading conditions.


※ 引述《qlman (Qlman)》之銘言：
: 規範 2.3.4
: (a) 任何抵抗地震力構材之計算剪力強度低於該構材於設計載重併合地震效應
: 之撓曲強度所對應之剪力者,其剪力折減因數為0.60..
: 有誰可以幫我翻譯這一段文字....(老k~~你還躲~~)
: =====我補充一下好了=====
: Vn = (Vc + Vs) < Vu = Mu/Ln From (Load factor (DL, LL, E) )
: then phi = 0.60...
: 我想要說的是這樣的邏輯....Vn已經比較小了(要放大斷面或加大配筋)
: phi還從0.75降成0.60...這是落井下石嗎???
: 越來越覺得401-96像天書....有誰可以代購ACI-NOTE嗎???
: =======
: 補個花絮好了....
: etabs v9.7.x版.... 它雖然是提供了最新版的規範設計....
: 但是...它的設計結果跟V8.5版的結果是一樣....
: 這說明什麼呢???
: CSI踹共....哈~~~
