Seismic Performance of Damaged Dovetail Joints with Different Damaged Degrees in Timber Frames

A Technique for Seismic Rehabilitation of Damaged Steel Moment Resisting Frames

Moment resisting frames as one of the conventional lateral load resisting systems in buildings suffer from some limitations including code limitations on minimum span-to-depth ratio to ensure the formation of plastic hinges with adequate length at beam ends. According to seismic codes, in ordinary steel moment resisting frames the minimum span-to-depth ratios should be limited to 5 and in speci...

Fe Analysis of Steel Links for Seismic Resistant Timber Frames

Performance of Corrosion-Damaged HSC Beams Strengthened with GFRP Laminates

This paper presents the results of an experimental program conducted for evaluating the performance of corrosion damaged HSC beams strengthened with GFRP laminates. Five Beam specimens of size 150x250x3000 mm were caste and tested for the present investigation. One beam specimen was neither corroded nor strengthened to serve as reference. Two beams were corroded to serve as corroded control. A ...

the effect of task cognitive complexity and time limit on the performance of the learners with different proficiency levels in second language writing skill

this study investigated the effects of manipulating the cognitive complexity of tasks along +/- few elements and the time limits on l2 learners writing performance. to conduct the study, 60 iranian efl learners with two levels of proficiency, low and high intermediate, were selected and assigned to three groups based on the time devoted to task completion. the participants performed both a simp...

Seismic Performance of RC Frames Irregular in Elevation Designed Based on Iranian Seismic Code

Setback in elevation of a structure is a special irregularity with considerable effect on its seismic performance. This paper addresses multistory Reinforced Concrete (RC) frame buildings, regular and irregular in elevation. Several multistory Reinforced Concrete Moment Resisting Frames (RCMRFs) with different types of setbacks, as well as the regular frames in elevation, are designed according...
