The comparison of nonlinear dynamic analysis pushover analysis provides good prediction of seismic demands for low-rise structures having uniform distribution of in-elastic behaviour over the height. It was also recommended to implement pushover analysis with caution and judgment considering its many limitations since the method is approximate in nature and it contains many unresolved issues that need to be
Earthquake engineering has become an important aspect of structural engineering, especially after the recent seismic incidents that took place in Chile, Mexico or New Zealand. These events shook the engineers from within and they are now expected to deliver stronger structure that can withstand such hazards. With latest tools and technology and of course BIM analysis methods, it will now be easier for engineers to design or build more earthquake resistant buildings. So what is seismic analysis and how can BIM analysis aid engineers for it? Calculating the response of a building structure during earthquake is what seismic analysis method is all about.
Generally Equivalent static analysis is not adopted for high rise buildings. Practically it does not take into account all the factors that are importance of foundation condition. The equivalent static analysis is used to design small structures. In this method only one mode is considered for each direction. Earthquake resistant designing for low rise structures the equivalent static method is enough.
I had to design a 30 storey residental structure in ETABS and SAP as well as performed VBA modeling in Excel to obtain the Center of Rigid (COR) of the building to optimize steel requirements from the effect of torsion. Also, I was assigned to design two foundation types: shallow foundation and reinforced concrete pile foundation. Additionally, I had to prepare and delivered presentation on the importance of quality checks and safety at the construction site. Armed with sound training in basic theories and applied technology, I put them into pratice by participating many summer interships. These practical experiences gave me opportunities to involve in all practical steps in design and construction of structures.
Elasto-Plastic Seismic response of RC continuos bridge with foundation-pier dynamic interaction (Bo, Chen, Yu) 2015,18, 6, Advances In Structural Engineering Using materials with high quality can help the bridge strengthen its durability. In this article, the shallow foundation is often employed as the base for bridges. And due to some natural phenomenon, the shallow foundation experiences plastics deformation. No matter how durable the strength of matrials used in building up brides, if the very own foundation is not strong, the bridge itself is not strong enough to withstand some phenomenons. This article shows that the study of soil-structure interaction (SSI) will help to maintain a proper foundation for bridges.
This requires a knowledge of the external forces and thermal transients experienced by the structure during service operation and representation of the cyclic and creep deformation properties of the materials of construction in terms of model constitutive equations irrespective of whether the local stress-strain is determined by approximate analytical solutions or finite element analysis, the constitutive model options are generally the same  
A structural engineer needs to develop an effective lateral load resisting system, which would prevent collapse and damage to life and property. In the event of an earthquake, the structure is subjected to lateral forces which are generated by the structure’s inertia resisting motion. These forces can be very high in magnitude. To design a structure to remain elastic during earthquake would be impractical and uneconomical. A number of techniques and
• The development of adequate stress analyses for brick masonry. • To develop a deeper understanding of the behavior of brick masonry based on experiments and computer methods. • To fulfill the above aim the material characterization of brick masonry is carried out through experiments performed in material testing laboratory. 1.2 SCOPE OF WORK Goals of the project: The goal of this project is to do macro computer modeling of brick masonry under seismic loading in order to convert the highly indeterminate and nonlinear behavior of brick masonry into something that can be understood with an acceptable degree of certainty and in order to define and describe the behavior of masonry under seismic loading. Deliverables: • Extraction of mechanical properties of unreinforced brick masonry.
3. METHODS FOR ANAYLSIS 3.1 IS 1893 (Part 1): 2002 Earthquake and its occurrence and measurements, its vibration effect and structural response have been continuously studied for many years in earthquake history. Since then the structural engineers have tried hard to examine the procedure, with an aim to counter the complex dynamic effect of seismically induced forces in structures, for designing of earthquake resistant structures in a refined and easy manner. This re-examination and continuous effort has resulted in several revisions of Indian Standard: IS 1893: (1962, 1966, 1970, 1975, 1984, and 2002) code of practice on the “Criteria for Earthquake Resistant Design of structures” by the Bureau of Indian Standards (BIS), New Delhi. It was adopted after the draft finalized by the Earthquake Engineering Sectional Committee had been approved by the Civil Engineering Division Council.
