[ 3 ] - The Comparison of the IDA and ET on Steel Structures Rehabilitated by Isolators

Endurance time (ET) method is a relatively new performance-based earthquake method for structural evaluation and design. In this method, the structure is subjected to a gradually intensifying accelorogram(s) and its performance is assessed based on the maximum time duration that it can meet the specified performance objectives. Using moment-resisting and braced frames which are rehabilitated by...

[ 4 ] - نقش و جایگاه فناوری اطلاعات در بخش ساختمان

بهره مندی از اطلاعات و چگونگی به کارگیری آن، با هدف دستیابی به توانایی های بیشینه، اساسی ترین موضوع دنیای کنونی است. میزان موفقیت هر سازمان در جهان امروز در گرو میزان بهره مندی آن سازمان از روش های مختلف راهبردی ـ اجرایی است، که آن نیز با چگونگی دسترسی به اطلاعات ـ و به عبارتی چگونگی دانایی آن سازمان ـ ارتباط مستقیم دارد. بخش ساختمان با توجه به موفقیت های ویژه ـ که به دور ماندن آنها نیازمند تحو...

[ 5 ] - برآورد احتمالاتی ظرفیت سکوهای دریایی نوع جاکت به‌کمک روش تحلیل امواج تصادفی افزایشی

based assessment of offshore jacket type platforms against wave loading. This approach can be employed to obtain a more realistic estimate for the ultimate capacity of offshore platforms, in comparison to the commonly used push-over analysis. On the other hand, ocean and sea waves are both random they are irregular in shape, height, speed, period and directions. Therefore, one of the most impor...

[ 6 ] - ارزیابی رفتار لرزه‌ای سکوهای پایه ثابت با استفاده از روش زمان دوام

Evaluation of seismic behavior of offshore platforms is one of the important design steps in seismic regions. Nevertheless, because of complication and time cost of these methods, engineers usually do not study them deeply. Endurance Time (ET) method is a good solution for this problem. In this method, with acceptance of a reasonable region of errors, the time of analysis can be reduced conside...

[ 7 ] - INVESTIGATION OF NON-LINEAR CYCLES’ PROPERTIES IN STRUCTURES SUBJECTED TO ENDURANCE TIME EXCITATION FUNCTIONS

Endurance Time Method (ET) is a dynamic analysis in which structures are subjected to intensifying accelerograms that are optimized in a way that seismic performance of structures can be estimated at different hazard levels with the best possible accuracy. For the currently available ET accelerograms, regardless of the shaking characteristic, an excitation level is recognized as a representativ...
