Structural walls commonly used as efficient structural elements to resist lateral and vertical loads. Diverse performance of bearing wall system in past earthquakes, motivates investigation on the adequacy of current seismic design provision for these walls. This study considers seismic performance of model walls of bearing wall and building frame systems designed as ordinary and special struct...

For some electrostatic precipitators, profiled steel sheets are used as casing wall which is subjected to both bending and vertical compression. By nonlinear finite element method, the influences of structural parameters on load bearing capacity of profiled steel sheet wall were investigated. For the loading path, the uniform transversal pressure was applied firstly, and then the vertical compr...

in shallow foundations, the third bearing capacity factor, n, has been found to show a decreasing tendency with increasing the foundation size. it is supported by experimental observations and related mainly to stress level dependent nature of the soil. on the other hand, the bearing capacity is often obtained theoretically without consideration of the foundation vertical displacements. in thi...

The importance of indoor mobile connectivity has increased during the last years, especially Covid-19 pandemic. In contrast, new energy-efficient buildings contain structures like low-emissive windows and multi-layered thermal insulations which all block radio signals effectively. To solve this problem with connectivity, we study passive antenna systems embedded in walls low-energy buildings. W...

In this study the fire test was performed to investigate mechanic behaviors and failure patterns of precast normal weight concrete (NWC) lightweight (LWC) walls with three types commonly used steel connectors, namely dry (61), wet (81), bearing (56E) connectors. For LWC wall specimens, on lateral application tension, cracking load values dry, wet, bearing-type connectors were 95.1%, 86.3%, 83.0...

The columns of frame structures are the key load-bearing components and the exterior columns are susceptible to attack in terrorist blasts. When subjected to blast loads, the columns would suffer a loss of bearing capacity to a certain extent due to the damage imparted which may lead to their collapse and even cause the progressive collapse of the whole structure . The concrete-filled steel col...

Progressive collapse is defined as the spread of an initial damage from one member to another, leading to extensive partial or total collapse of the structure. In this research, the potential of progressive collapse due to a sudden removal of vertical load-bearing elements in reinforced concrete buildings structures with different floor plans such as geometrical regular and irregular floor plan...

Background The mechanism of offloading plantar pressure with a TCC is by redistributing weight-bearing load across the entire plantar surface of the foot and increasing the plantar surface contact area [1]. An additional mechanism is by transfer of load to the cast walls however these studies relied on indirect methods [2-4]. No previous research has directly measured the load on the cast wall....

Building waste is a critical issue in current construction. Innovative design strategies are required to reduce the depletion of valuable materials and resources through providing flexible and versatile structures. This study focuses on the development of an industrial, flexible, and demountable wall panel construction system. The panel system consists of concrete blocks with steel connectors t...
