“…During the experimental response of the UCSD full-scale 7-story wall test [14], the important effect of the higher modes was observed, though their contribution was not so adequate to cause formation of a plastic hinge above the base. Regarding historical evidences, historical records do seem to indicate plastic hinge formation at intermediate heights [15,16].…”

SUMMARYThis paper explores the notion of detailing reinforced concrete structural walls to develop base and midheight plastic hinges to better control the seismic response of tall cantilever wall buildings to strong shaking. This concept, termed here dual-plastic hinge (DPH) concept, is used to reduce the effects of higher modes of response in high-rise buildings. Higher modes can significantly increase the flexural demands in tall cantilever wall buildings. Lumped-mass Euler-Bernoulli cantilevers are used to model the case-study buildings examined in this paper. Buildings with 10, 20 and 40 stories are designed according to three different approaches: ACI-318, Eurocode 8 and the proposed DPH concept. The buildings are designed and subjected to three-specific historical strong near-fault ground motions. The investigation clearly shows the dual-hinge design concept is effective at reducing the effects of the second mode of response. An advantage of the concept is that, when combined with capacity design, it can result in relaxation of special reinforcing detailing in large portions of the walls.

“…Do sada je proveden velik broj analiza armiranobetonskih nosivih elemenata i spojeva. S obzirom na značajni napredak u području numeričkih metoda proračuna, već sada je potvrđena učinkovitost vodećih računalnih programa za predviđanje odziva konstrukcija [1][2][3][4][5][6]. U proteklom su desetljeću provedena razna istraživanja o međusobnoj interakciji između ploča i posmičnih zidova [7][8][9][10] sa svrhom dobivanja što više podataka.…”

Numerička ocjena spoja nosivog zida i ravne ploče U radu je provedena analiza odziva spoja vanjskog posmičnog zida i ravne ploče za slučaj ravninskog reverzibilnog cikličnog opterećenja. Provedena je numerička analiza spoja vanjskog zida i ploče na uzorcima umanjenima na jednu trećinu od prvobitne veličine, uz primjenu dviju vrsta rasporeda armature u spoju. Razmatran je konvencionalan raspored i predloženi nekonvencionalan raspored razrade armature spoja. Ustanovljeno je da se predloženi nekonvencionalni tip armiranja spoja bolje ponaša od konvencionalnog tipa. Numerical evaluation of structural wall -flat slab connectionThe response of the exterior shear wall to flat slab connection, subjected to the inplane reversible cyclic load, is analyzed in the paper. The numerical analysis of the exterior wall-slab connection specimens scaled down to one third of the original size, with two types of joint detailing patterns, was conducted. The conventional pattern and a proposed nonconventional joint reinforcement detailing pattern were considered. It was established that the performance of the proposed nonconventional type of joint detailing is better compared to that of the conventional type.

“…The available literature describing hysteretic behavior of common structure types was consulted to establish a framework of generalized hysteretic models for regional seismic loss assessment [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. The objective was to develop models that would provide a pragmatic balance between comprehensive consideration of diverse hysteretic behavior patterns, while maintaining an appropriate level of generality and simplicity in the output for use in regional analyses.…”
