Evaluasi Kinerja Struktur Gedung Bertingkat Dengan Pemodelan (3D) Berdasarkan Analisis Beban Dorong (Pushover Analysis)”. pushover adalah prosedur statis yang menggunakan teknik nonlinier disederhanakan untuk memperkirakan deformasi struktural seismic atau gempa bumi, kemudian analisis mensimulasikan fenomena ini dengan menerapkan beban sampai pelelehan (sendi plastis) pertama dalam struktur di...

torsion of many symmetric structures, which were designed based on the seismic codes, is due to their asymmetricity induced during inelastic behavior. although the structure was designed symmetrically assuming elastic based criteria, different factors such as material inconsistency in structure, construction details discrepancy and construction errors may result in asymmetric behavior in inelas...

The proposal lateral load pattern for pushover analysis is given in two forms for symmetric concrete buildings: 1-(X/H)0.5 for low-rise and mid-rise buildings, 2- Sin(ΠX/H) for high-rise buildings. These two forms give more realistic results as compared to conventional load patterns such as triangular and uniform load patterns. The assumed buildings of 4, 8, 12, 16, 20 and 30 story concrete bui...

A large part of the building stock in seismic-prone areas worldwide are masonry structures that have been designed without seismic design considerations. Proper seismic assessment of such structures is quite a challenge, particularly so if their response well into the inelastic range, up to local or global failure, has to be predicted, as typically required in fragility analysis. A critical iss...

Irregular buildings make up a large portion of  urban infrastructure. Presence of irregularities can be due to architectural and  user changes in building stories. Main objective of this article is evaluate seismic performance of structures with vertical irregularities. Seismic responses are obtained by enveloping peak inelastic responses resulting from pushover analyses according to provided p...

The main objective of this study is to compare the structural members capacity between different types bridges structures under seismic load. results modal analysis showed that models box girder bridge, precast T and U steel bridge had higher values natural frequency comparing with others Pushover in transvers direction bent No. 2 which was located middle superstructure displaced more than 1 3....

Non-linear dynamic time history analysis is considered as the most advanced and comprehensive analytical method for evaluating the seismic response and performance of multi-degree-of-freedom building structures under the influence of earthquake ground motions. However, effective and accurate application of the method requires the implementation of advanced hysteretic constitutive models of the ...
