Rationalized structural systems for diverse applications
… Europe and developing countries, concrete panel systems were gradually established as the primary building prefabrication method. However, concrete panel buildings demonstrated in time resistance to change, lack of adaptability to diverse sites and contexts and inefficiency in the use of the …

Conceptual design of suspended structural systems
This thesis investigates the use of suspended structural systems. This is done by performing a conceptual design for the proposed new Civil and Environmental Engineering building at the Massachusetts Institute of Technology. It begins with site considerations and owner requirements and progresses …

Identification of structural systems from measured response
… estimation of finite element models of complex structural systems using measured response. The developed method computes the element, constitutive parameters of a finite element model of a structure by finding a constrained nonlinear minimum of the difference between the measured response of the …

Structural systems and conceptual design of cantilevers
… are amazing feats for the built environment, and structurally, present many opportunities. However, conceptual cantilever design can be a difficult task for Architects and Structural Engineers because there are many structural systems or strategies designers could choose to carry loads to …

Stochastic dynamic response of wood structural systems
… energy dissipation mechanisms of wood joints and structural systems must be known and the hysteretic behavior modeled properly. This dissertation presents a general hysteresis model for wood joints and structural systems, based on a modification of the Bouc-Wen-Baber-Noori (BWBN) model. The …

Robust analysis and control of smart structural systems
"For successful development of smart structural systems to control structural vibrations, the actuator/sensors should be configured at locations giving maximum control effectiveness, and the systhesized controller has to be robust for uncertainties such as uncertain parameters and saturating …

An overview of progressive collapse in structural systems
… more terrorist action in the future, it is clear structural design must include progressive collapse mitigation. The most critical abnormal loadings that have potential to cause progressive failure are blast and impact. These loads are impulsive and dynamic in nature with the potential to induce …

New structural systems in small-diameter round timber
Trees, when used as structural elements in their natural, round form, are up to five times stronger than the largest piece of dimensioned lumber they could yield. Additionally, these whole-timbers have a lower effective embodied carbon than any other structural material. When combined into …

Residual flexibility methods for decoupled analysis of integrated structural systems
Methods of dynamic analysis of large structural systems used in aerospace applications are examined. Full-system solutions are undesirable due to computational cost and logistics issues. Traditional substructuring methods effectively reduce system size through truncation of component modes, but …

Fatigue and fracture reliability and maintainability process for structural systems.
… design decisions and reliability assessments of structural systems. System reliability can be improved by a maintenance program of periodic inspection and repair or replacement of damaged members. But there are also uncertainities introduced by the inspection process. In summary, the …

Damage detection and assessment of structural systems from measured response
A new damage detection algorithm is developed based on a system identification method. The algorithm can be used as a non-destructive diagnostic technique to aid in decisions of repair and rehabilitation of existing structures. The developed algorithm is able to detect and assess damage in a …
