Modular Structures

The construction industry has tried out a variety of trends in its field to bring out innovative, economic, efficient and sustainable infrastructure to meet the growing demand. One such development is the off-site manufactured modular steel buildings. The practice reduces the construction period as well as reduces wastage of resources. It was extensively used for low rise structures earlier, but due to increasing urban construction demand the practice is preferred nowadays in high rise structures too. For the high rise structures the lateral stability needed to be well looked into as there may arise a mass irregularity, structural irregularity, discontinuity etc. Psychological acceptance of such construction practice by the public is also not assured as they are not well aware of the advantages and use of the practice. And hence there is a need to conduct detailed and thorough investigation on its contradiction part to seismic performance. The modular construction consists of different structural systems and load transferring mechanisms. The integration of many materials and elements to modular structures are also discussed in various papers. But regarding lateral force resistance of its structural and non-structural components only limited research is conducted. Further research is required. The aim of the study is to provide a collective critical review on individual units or components of the structural system and their effects contributing to seismic resistance.

Moderate Seismicity

The lateral load-resisting system of high-rise buildings in regions of low and moderate seismicity and strong wind such as the typhoon in the Korean peninsula considers the wind load as the governed lateral force so that the practical structural engineer tends to skip the evaluation against the seismic load. This study is to investigate wind-designed steel diagrid buildings located in these regions and check the possibility of the elastic design of them out. To this end, first, the diagrid high-rise buildings were designed to satisfy the wind serviceability criteria specified in KBC 2016. Then, the response spectrum analyses were performed under various slenderness ratio and wind exposures. The analyses demonstrated the good seismic performance of these wind-designed diagrid high-rise buildings because of the significant over-strength induced by the lateral load-resisting system of high-rise buildings. Also, the analysis results showed that the elastic seismic design process of some diagrid high-rise buildings may be accepted based on slenderness ratios in all wind exposures.

Main Component

In high-rise concrete structures, the elevator or stairs which located in the middle of the building are always put into the RC core walls. It not only meets the requirements of the function of usage, but also makes the core walls bear most of the lateral force and becomes the main component in the whole structure that resists the lateral force. Therefore, the seismic performance of RC core walls is of great concern to engineering. At present, there is little experimental study on measures of improving the seismic performance of RC core walls. In this paper, firstly, a new type of construction measure is put forward to improve its seismic performance. Secondly, through the experimental study on one 1/6 scale core walls with concealed bracings and one 1/6 scale normal core walls under the low cyclic loading, the effect of concealed bracings on bearing capacity, stiffness, ductility, hysteresis, failure phenomena and energy dissipation of concealed bracings are discussed. The experiment shows that the seismic performance of RC core walls with concealed bracings is improved remarkably.

Modular Structures

Modular structure is a new type of steel building with special construction to shorten the construction period and bring other benefits. Some studies on seismic performance of modular structures were introduced. In order to meet much higher seismic requirements with less steel usage, a new type of pretensioned modular frame was proposed, which can develop a more rigid connection between modules. A quasi-static loading test was performed on a full-scale pretension assembled framed modular system, which demonstrated seismic performance of modular connection can be improved through an effective connection. Finally, some technical proposals have been discussed in structural arrangement, calculation method as well as lateral resistant system.

Margin Of Safety

The tension-only braced frames (TOBFs) are widely used as a lateral force resisting system (LFRS) in low-rise steel buildings due to their simplicity and economic advantage. However, the system has poor seismic energy dissipation capacity and pinched hysteresis behavior caused by early buckling of slender bracing members. The main concern in utilizing the TOBF system is the determination of appropriate performance factors for seismic design. A formalized approach to quantify the seismic performance factor (SPF) based on determining an acceptable margin of safety against collapse is introduced by FEMA P695. The methodology is applied in this paper to assess the SPFs of the TOBF systems. For this purpose, a trial value of the R factor was first employed to design and model a set of TOBF archetype structures. Afterwards, the level of safety against collapse provided by the assumed R factor was investigated by using the non-linear analysis procedure of FEMA P695 comprising incremental dynamic analysis (IDA) under a set of prescribed ground motions. It was found that the R factor of 3.0 is appropriate for safe design of TOBFs. Also, the system over strength factor (Ω0) was estimated as 2.0 by performing non-linear static analyses.

The Impact

For construction sites within cities, which require fast construction because of restrictions in road occupation time, or for other occasions where construction period is an important factor because of similar reasons, application of a modular construction method using precast members is efficient in terms of shortening the construction period. The substructures of bridges are normally constructed using cast-in-place, which has been a major cause of delays in construction. Application of a modular construction method could decrease the occupation time in the sites. A prime example is the Accelerated Bridge Construction (ABC) by the Texas Department of Transportation (TDOT) and Federal Highway Administration (FHWA). Precast members are the key components of ABC. The main purpose of this paper is to provide clear seismic performance standards for precast bridge piers. Current seismic design codes require force-based design checks and provide qualitative evaluation of the overall structure. They do not provide specific qualitative criteria for individual structures with particular types. Previous research has been focused on reinforced-concrete bridge piers, while lacking on research towards prefabricated bridge piers with continuous reinforcements. In order to quantitatively evaluate the seismic performance level of prefabricated bridge piers, the seismic performance was quantitatively suggested in accordance with the classification of four which are operational, immediate occupancy, life safety, and collapse prevention. These criteria are cracking of cover concrete, crushing of cover concrete, yielding of axial steels, and fracture of axial steels. Based on the given seismic performance evaluation criteria, evaluation and verification were conducted on four prefabricated bridge piers with continuous reinforcement that have undergone quasistatic cyclic experiments. The moment-curvature analysis model was constructed for the parametric study and verified through experimental results. Based on the developed M-Phi model, prefabricated bridge piers with continuous reinforcement, which were designed force-based using response correction factor, were evaluated. In addition, parametric study was also conducted focusing on concrete strength, magnitude of prestress, and transverse reinforcement. Depending on the level of individual performance produced by ranges of these variables within possible runs on actual piers, the impact of 3 variables was analyzed. Furthermore, in response to changes in each variable, the impact on the relevant seismic performance level was verified through response spectrum analysis.
