Description

Technical Field

[0001] The present application relates to the technical field of testing the lateral resistance performance of panel walls, and in particular to a loading device and a testing method for the lateral resistance performance of panel walls. Background Art

[0002] With the continuous evolution of building structures and systems, traditional load-bearing wall structures are gradually being replaced by beam- and column-based load-bearing systems, and wall thicknesses are also decreasing. In existing buildings, various types of panel wall structures are widely used to divide building spaces. Although the structural performance of walls has weakened during this transformation, panel walls still make a significant contribution to the lateral resistance of the overall framework. Therefore, accurately and effectively measuring the lateral resistance of panel wall structures is crucial to ensuring the safety and reliability of building structures.

[0003] Due to the limitations of testing equipment, most existing research focuses on testing the seismic performance of the overall frame with embedded panel walls, while independent research on the lateral resistance of pure panel walls is relatively scarce. Summary of the Invention

[0004] The present application provides a device for loading the lateral resistance of a panel wall, comprising a reaction frame, an articulated frame and a hydraulic device. The articulated frame comprises two base plates fixed at intervals on the reaction frame, two supporting columns and a supporting beam. The bottom ends of the two supporting columns are respectively arranged on the two base plates, the supporting beam connects the upper ends of the two supporting columns, the loading end of the hydraulic device is connected to the supporting columns, and the fixed end of the hydraulic device is connected to the reaction frame. The hydraulic device includes a load sensor for monitoring the load value applied by the hydraulic device.

[0005] The present application provides a method for testing the lateral resistance performance of a panel wall, comprising: placing the panel wall to be tested in an articulated frame of a panel wall lateral resistance performance loading device according to any embodiment of the present disclosure, and a hydraulic device providing a horizontal load to achieve measurement of the lateral resistance performance of the panel wall.

[0006] The panel wall lateral resistance loading device and testing method according to some embodiments of the present disclosure can bring beneficial technical effects, such as:

[0007] 1. The panel wall lateral resistance loading device according to some embodiments of the present disclosure utilizes a modular installation design, making it simple and convenient to operate. Each component of the device is constructed from common building materials, resulting in a low overall cost, a simple structure, and easy fabrication. Furthermore, the components are primarily connected via bolts, making installation quick and efficient.

[0008] 2. The lateral resistance loading device for panel walls according to some embodiments of the present disclosure can effectively simulate the restraining effect of beam and column components on the panel wall edges. By symmetrically arranging column limit angles, beam limit angles, and base limit angles on the supporting columns, supporting beams, and base, and adjusting the limb-back distances of each limit angle to be consistent with the wall panel thickness, the actual restraint of the beam and column components on the panel wall edges can be highly restored. In addition, the steel base plate, supporting columns, and supporting beams are connected by hinges to form an articulated frame structure. This design not only effectively simulates the actual boundary conditions of the panel wall, but also cleverly eliminates the coupling effect between the peripheral frame and the lateral resistance of the panel wall, thereby achieving accurate measurement of the lateral resistance of the panel wall.

[0009] 3. The lateral resistance loading device for panel walls according to some embodiments of the present disclosure has extremely high flexibility in size adjustment. The limiting angle steels and supporting beams both adopt a segmented design, which can be flexibly adjusted according to the height and width of the panel wall to be tested to meet the testing requirements of panel walls of different sizes. At the same time, oblong holes are opened in each limiting angle steel so that the distance between the limbs of the limiting angle steel can be accurately adjusted according to the thickness changes of the panel wall to be tested. This design significantly improves the adaptability of the loading device, effectively solves the problem that traditional loading devices cannot meet the testing requirements of different specimen sizes due to fixed dimensions, and greatly reduces testing costs.

[0010] 4. According to some embodiments of the present disclosure, the panel wall lateral resistance loading device has a high-precision load sensor integrated inside, which can read the horizontal load data applied to the wall in real time and accurately, providing a strong guarantee for the accuracy of the test results.

[0011] 5. During the loading process, when the wall panel undergoes lateral displacement, its overall height will decrease as the lateral displacement increases, causing the preset loading point height to also decrease. In order to ensure that the lateral load can always be accurately applied, the plate wall lateral resistance performance loading device according to some embodiments of the present disclosure has an innovatively designed actuator connection joint. Through the actuator connection joint, when the horizontal load acts on the wall panel, the pin can move freely up and down in the third oblong hole, thereby dynamically adjusting the position of the loading point relative to the connection joint, ensuring that the horizontal load is always applied to the predetermined position of the support column. , thereby effectively avoiding load deviations caused by height changes, significantly improving the accuracy and reliability of the test results, and providing a strong guarantee for the accurate evaluation of the lateral resistance performance of the plate wall.
