Moment Resisting

The rapid growth of urban population and limited land space have greatly influenced the development of high-rise structures. Lateral loads have an important effect on the design as the building height increases. In order to resist lateral loads, safety and minimum damage should be the prime concern when designing tall buildings. To meet these requirements, the structure should have adequate lateral strength and lateral stiffness and sufficient ductility. Among the various structural systems, shear wall systems or moment resisting frame systems could be a point of choice for designers. Thus, it is important to review and observe the behavior of these systems under seismic effect. This study compared the seismic response of the above structural systems using a case study application at variable seismic zones (Zone 2B, Lebanon Zone, Zone 3, and Zone 4) and at different building stories (Eight and 12-story building). The seismic response is measured in term of time-period, maximum story displacement, maximum story drift, amount of steel and concrete needed. The outcome of this study portrayed that a shear wall system is more efficient in terms of cost and lateral load resistivity regardless of the building height and in the four seismic zones mentioned before.

Collapse Probability

The seismic performance of ordinary reinforced concrete shear walls, that are commonly used in high-rise residential buildings in Korea (h < 60 m), but are prohibited for tall buildings (h ≥ 60 m), is evaluated in this research project within the framework of collapse probability. Three bidimensional analytical models comprised of both coupled and uncoupled shear walls exceeding 60 m in height were designed using nonlinear dynamic analysis in accordance with Korean performance-based seismic design guidelines. Seismic design based on nonlinear dynamic analysis was performed using different shear force amplification factors in order to determine an appropriate factor. Then, an incremental dynamic analysis was performed to evaluate collapse fragility in accordance with the (Federal Emergency Management Agency) FEMA P695 procedure. Four engineering demand parameters including inter-story drift, plastic hinge rotation angle, concrete compressive strain and shear force were introduced to investigate the collapse probability of the designed analytical models. For all analytical models, flexural failure was the primary failure mode but shear force amplification factors played an important role in order to meet the requirement on collapse probability. High-rise ordinary reinforced concrete shear walls designed using seven pairs of ground motion components and a shear force amplification factor ≥ 1.2 were adequate to satisfy the criteria on collapse probability and the collapse margin ratio prescribed in FEMA P695.

The paper presents an application of the Extended Energy-dependent Generalized Bouc–Wen model (EEGBW) to simulate the experimental cyclic response of Cross-Laminated Timber (CLT) panels. The main objectives of the paper are assessing the sensitivity of the quadratic error between experimental and numerical data to the EEGBW parameters, showing the fitting performance of the EEGBW model in matching the experimental cyclic response of CLT panels, highlighting the stability of the model in nonlinear dynamic analysis with seismic excitation. The research proves that the considered Bouc–Wen class hysteresis model can reproduce the hysteretic response of structural arrangements characterized by pinching and degradation phenomena. The model exhibits significant stability in nonlinear dynamic analysis with seismic excitation. The model’s stability and versatility endorse its application to simulate structural systems’ dynamic response when Finite Element modelling might be an impractical choice.

Lateral Strength

Shear wall systems are the most commonly used lateral load resisting systems in high seismic zones because they provide significant lateral strength, stiffness, and deformation capacity. The work further investigates the seismic performance of different kinds of shear walls. Classified and brief comments about the seismic performance and the exist drawback of different kinds of shear walls and its application are conducted. Lastly, some useful suggestions and a new structure are proposed for the further research.
