Building Condition

This paper introduces the concept of a BIM-based life-cycle management system for reinforced concrete buildings. The system allows one to compute a prognosis of the building’s condition taking into account the material properties of individual components, the environmental load as well as measurement data from current inspections. This prognosis then forms foundations for scheduled maintenance and repair actions in an economically efficient way. A particularly important feature of the presented system is that all input data as well as the computational results are associated with a (full) 3D Building Information Model (BIM) of the construction. In this way, an easy localization of the information is achieved facilitating both the data collection and the estimation of the building condition for engineers involved in inspection planning, inspection or the scheduling of repair actions. To further facilitate data input and interpretation, a hierarchic level-of-detail approach is employed for structuring the building model, ranging from building level down to individual hot spots. Additionally, the integration of a meta-model allows the flexible adaption of the semantic data model to specific buildings types or the particular needs of the users.

The Impact

Gorkha Earthquake in 2015 has impacted considerably in the design and construction of buildings in Nepal. Strength and Safety of life and constructions have become the prime concerns of the government and the public. Regulation is required to achieve the strength and safety in the constructions. Hence, a need for revision of building codes has been felt and Nepal Building Code, NBC105 has been revised. This paper presents the impact of the revised code on seismic load estimation for low rise reinforced concrete buildings. For the assessment of the impact linear and non- linear static and linear dynamic analysis of reinforced concrete residential buildings of two storey and four Storey has been taken subjected to Indian Standard Codes IS 1893: 2002, IS 1893:2016, Nepal Building Codes NBC 105: 1994 and NBC 105: 2020. The buildings were modeled and analyzed in SAP2000. The response of the buildings such as time period, base shear, drifts, and storey forces from the application of the four codes was compared. The comparison of the results shows that the structural response of the building under the revised NBC105:2020 is 60% to 65% higher compared to the previous code NBC105:1994.

Nonlinear Static Procedure

One design alternative of earthquake resistant building is Partial Capacity Design (PCD) method. Unlike the commonly used capacity design method, PCD allows a safe failure mechanism which is called partial sidesway mechanism. In this mechanism, all beams and some columns are allowed to experience plastic damages while some selected columns are designed to remain elastic (called elastic columns). A new approach to predict the required strengths needed to design each structural member, called modified-PCD (M-PCD) is proposed. In this research six- and ten-story reinforced concrete buildings were designed using M-PCD, and their seismic performances are investigated. The base shear force resisted by the elastic columns was set to approximately 70% of the total base shear. Both nonlinear static procedure (NSP) and nonlinear dynamic procedure (NDP) are used to analyze the structures. The results show that the expected partial side sway mechanism is observed, and the drifts of the buildings are acceptable.

Seismic Loadings

The multiple earthquakes have proved the effect of chained masonry walls on the seismic behavior of multistoried reinforced concrete buildings. The chained masonry walls have been considered one of the types of masonry infill walls but without gaps. This participation came intending to study this effect through the modeling of several two-dimensional frames for a multistoried reinforced concrete building, taking into account the hollow brick walls, which represent the most common type in Algeria. We analyzed the proposed models using ETABS finite element software, relying on the response spectrum method and respecting the most important requirements according to the applicable Algerian Seismic Code. After analysis of the different models, the results have been compared according to the parameters of the period, base shear, lateral displacement, and stiffness. Through a critical synthesis of the results, we concluded that these walls could significantly affect the seismic behavior of this type of buildings. Moreover, the neglect of these walls in the modeling process can lead designers to have a false perception of the behavior of these buildings towards seismic loadings.
