There are still many problems remain to be solved in these aspects , such as behavior research on the lateral resistant of steel frame and connection etc . in this paper three 1 : 2 - scale steel frame specimens and eight full - scale steel frame connection specimens are tested on their behavior under cycle loading . there are six aspects as below on the problems of steel resident building researched : 1 pseudo - static force testing of eight full - scale connections , including top - seat angle connections , two web flange and top - seat connections and dog - bone connections are carried out for the first time in our country 本文針對鋼結構住宅體系中亟待解決的若干問題,完成了三榀1 : 2鋼框架模型和八個足尺比例的梁柱連接模型在低周往復荷載作用下的試驗,進行了以下幾個方面的深入研究: 1進行了頂底角鋼連接、帶雙腹板頂底角鋼連接等半剛性連接及狗骨式剛性連接這三種連接類型共八個原型試件的擬靜力試驗。

Therefore , the paper is dedicated to study a new type joint - top and seat angle with double web angles semi - rigid connection , which has good resistance to vibration on the base of large quantity of alien data . lt studies the damage mechanism under the quasi - static load , get this joint ' s performance parameter obtains the hysteresis curve , defines the hysteresis model and the parameter of the model 通過進行該種連接在單調荷載和周期荷載作用下的試驗,研究了該連接在擬靜力荷載作用下的破壞機理、獲得了有關該種的性能參數、做出了該連接的滯回曲線,并確定了滯回模型和模型參數。

The present findings of semi - rigid connections , the method for design of beam - to - column connections in the codes from china and other countries , and the character about semi - rigid connections , were briefly introduced in this paper . the simulated method of the m - r relation curve of semi - rigid connections , the computing equations about the initial stiffness and moment capacities of two kinds of top - seat angle connections , with and without double web - angle , were discussed 本文簡要地介紹了半剛性節點的研究現狀、各國規范梁柱連接的設計計算內容和方法、梁柱連接的類型和半剛性連接的特性,探討了頂、底角鋼、頂、底角鋼帶雙腹板角鋼兩種半剛性連接的m - _ r特征曲線及其擬合方法,頂底角鋼連接、帶雙腹板頂底角鋼連接初始剛度以及彎矩承載力的計算公式。

In the meanwhile , the semi - rigid connections can save steel capacity , and become a kind of not only economical , but also reliability connection . top and seat angle with double web angles semi - rigid connection is of performance , while few study has for complex destroy and many effect factors 頂底角鋼雙腹板連接由于其較好的性能,但由于其破壞的形式比較復雜而且影響因素較多在國內外研究中觸及很少,本基金項目正處于此初衷對其進行理論研究與實驗分析。

2 . pseudo - static force testing of twelve full - scale connections , including top - seat angle connections , two web flange and top - seat connections , extended - end - plate connections , slit - t steel connections and dog - bone connections are carried out for the first time in our country 2首次在國內大規模地進行了頂底角鋼連接、帶雙腹板頂底角鋼連接、外伸端板連接以及短t型鋼連接等半剛性連接以及狗骨式剛性連接這五種連接類型共十二個原型試件的擬靜力試驗。

However , “ rigid joint “ in the welded steel frame of the northridg earthquake occurred to a large quantity of brittle breakage . therefore , the paper is dedicated to study a new type joint - top and seat angle with double web angles semi - rigid connection 但美國northridge地震( 1994 )和隨后發生的日本阪神地震( 1995 )中焊接鋼框架剛性連接節點發生了大量的脆性破壞現象,人們開始將目光投向抗震性能良好的半剛性連接鋼框架。

For the top - and - seat angle connections considered in the paper , the large fatigue based plastic rotation capacity can be achieved 對于本文中所研究的頂底角鋼連接而言,可以取得較大的塑性轉角。

The paper is dedicated to study the low - cycle fatigue behavior of a certain semi - rigid connection : the top - and - seat angle 本文嘗試研究一種半剛性連接-頂底角鋼連接的低周疲勞性能。
