[0067]5%NaOHの加速老化試験の実行に際し、ガラス繊維の試験片は、高品質で損傷のない布から集めた。機械方向及び機械横断方向の両方から取った試験片を試験したが、各試験片は、長さ330mm、幅50mmであった。試験片は、蒸留水の5%NaOH(水酸化ナトリウム)アルカリ性槽内に28日間、放置浸漬し、各試験後に槽は取り替えた。試験片は、アルカリ性槽内で適切な状態に整えた後、少なくとも1リットルの蒸留水で、少なくとも10回先浄した。先浄後、布の試験片を、室温で7日間乾燥した。乾燥後、布の試験片を、把持スパン5インチで、2インチ/分の速度で張力試験した。
具体例
[0078]本発明及びその利点を、以下の具体例に関連付けて説明する。以下の例は、説明を目的にしたものであり、本発明の範囲を限定するものではない。以下の例では、上記方法を使用し、石積壁で、そして三層構成サンプルについて試験した。支持装置全体として相当に耐震補強が改良されたことを示す結果が得られた。
例1
[0079]図3は、軽く補強されたサンプルCMUブロック壁100(壁1)を、標準の20.3cm×20.3cm×40.6cm(8×8×16インチ)のCMU110で作ったものである。CMUは、砂1、タイプ1ポートランドセメント3、消石灰1と、専門家が使えるモルタル混合物を作れるだけの量の水とで構成されているタイプNのモルタルで作った。壁は高さ10段で、上部及び下部の2段は中央の6段より40.6cm(16インチ)広く、「I」字型を形成している。上部2段及び下部2段の全ブロックにはグラウトを一杯に詰め、試験の間に負荷フレーム(図4参照)からの荷重が巧く伝達されるようにし、壁の幅広の上部及び下部区画内で壁の損傷が起こる確率を減じた。#4の鋼製補強バー120を、中央の支台を取り囲むセル内に配置した。鋼製補強バーが入っている全ブロックには、グラウトを一杯に詰めた。9.525mm(3/8インチ)の面殻(faceshell)モルタル敷層を、積み終えグラウトを一杯に詰めたブロックに隣接するクロスウェブユニット付のCMUブロック上に用いて、グラウトが、隣接するセルへ流れ込まないようにした。Dur−o−wal接合補強130を、上部2段及び下部2段の間の積み上げ接合面に施した。
[0084]本発明の代表的な方法による本発明の代表的な補強装置によって補強したサンプル壁を、米国陸軍工学研究開発センターの建設工学研究実験室で、平面内剪断について試験した。図3−5に示すように、補強装置150を付けた壁サンプル100を、負荷試験フレーム160内に設置し、上部及び下部の試験片耳部102上に配したボルト締め鋼管162と、アイボルト166を使って負荷フレーム160に取り付けた鋼製チャネル及びロッド164とを使って、所定の位置でクランプした。負荷床試験フレーム160は、ポストテンション強化済みコンクリート反力強化壁と鋼製フレームで構成されていた。±20インチのストロークを有する49.9トン(110キップ(kip))油圧作動器(図示せず)を強化壁に取り付け、上部コンクリート梁168にボルトで取り付けられている鋼管170を通して、サンプル壁100に水平方向の力(HF)を加えた。±3インチのストロークを有する2つの22.86トン(50キップ)作動器(北及び南)(図示せず)を、鋼製フレームと水平方向鋼管170に取り付け、軸方向(垂直方向)荷重(FVS及びFVN)を掛け、壁試験片に掛かる死荷重をシミュレートした。作動器の油圧は、コンピューター制御した。
例2
[0088]補強装置を適用した第2壁サンプル200(壁2)を、壁サンプル1に関して説明したのと同じ方法を使って試験した。壁2は、例1で説明した材料及び手順に従って作り、壁2に適用した補強装置は、例1で説明した材料で作った。例1と例2の違いは、強化材の付着方法に関する違いだけである。壁2の補強装置を付着させる際に、第1ガラス繊維層を、2本の粗糸を有する布のよこ糸方向が、壁の下部に対して45°の角度に、上部左角(US)から下部右角(LN)まで走るように向けた。第2ガラス繊維層は、繊維層のよこ糸方向が、サンプル壁200の下部に対し垂直になるように向けた。
例3
[0091]補強装置が適用されている第3壁サンプル300(壁3)を、壁サンプル1及び2に関して説明したのと同じ試験方法を使って試験した。壁3は、例1で説明した材料及び手順に従って作った。壁3に適用した補強装置は、強化材に付着させたマトリックスの最後の層が、通常のQuickWall製品よりも砂を多く含んでいるQuickCrete製のQuickWall Sanded(商標名)材で構成されていることを除いて、例1で説明した材料組成で作った。
例4
[0095]図12に示すような三層構成サンプル400を、3個、標準的な8x8x16インチCMUを使って組み立てた。三層構成サンプル400は、3つのブロック402、404及び406を、中央のブロック404を3/4インチだけずらして、積み上げ接着して作った。3つの三層構成サンプルに適用した補強装置410は、マトリックス層が、通常のQuickWall製品とは異なるQuickWall Sanded(商標名)材料で構成されていることを除いて、上記例で説明した材料組成で作った。
結果
[0102]ARガラス布で補強した無機マトリックスを、上記壁のような支持構造体に塗り付ける利点は、変位限界を上げることによって、支持構造体に強度を付加し、構造体の性能を改良することである。これらの利点は、地震及び爆発に対する耐性を改良する結果となる。図7、9及び11に示す背骨状曲線は、考察中の支持構造体の工学的強度を表している。工学的強度は、背骨状曲線に写し出されたピーク負荷で定義される。工学的目的に関して言えば、工学的強度の方が、実測ピーク荷重よりも良い装置性能指標になるが、それは、ピーク荷重値を考える場合には存在することもしないこともある安全係数を組み込んでいるからである。
