Summary
In order to study the lateral resistance of reinforced glued-laminated timber post and beam structures, nine cyclic tests on full-scale one-storey, one-bay timber post and beam construction specimens were carried out. Two reinforcement methods (wrapping fiber reinforced polymer (FRP) and implanting self-tapping screws) and two structural systems (simple frame and knee-braced frame) were considered in the experimental tests. Based on the experimental phenomena and test results, feasibility of the reinforcement was discussed, contribution between different methods was evaluated, and the seismic performances of the specimens were studied. Results showed that both the two reinforcement methods could restrain the development of crack, and recover the strength, stiffness and energy dissipation capacity. It also showed that the lateral resistance could be improved significantly when the failed simple frame retrofitted by reinforcing the joint and adding knee-brace, and this approach can be very practical in engineering.

Summary
Nine cyclic tests were conducted on full-scale one-story, one-bay timber post and beam construction specimens to study the lateral resistance of reinforced glued-laminated timber post and beam structures. Two reinforcement methods, wrapping fiber-reinforced polymer (FRP) and implanting self-tapping screws, and two structural systems, simple frame and knee-braced frame, were considered in the experimental tests. Based on the observed experimental phenomena and the test results, the feasibility of the reinforcement was discussed; the contributions of different methods were evaluated; and the seismic performance of the specimens were studied. The results indicated that both reinforcement methods could limit the crack development and improve the strength, stiffness and energy dissipation capacity. The results also showed that the lateral resistance could be significantly improved by retrofitting a failed simple frame with joint reinforcement and a knee-brace, demonstrating that this approach can be applied in engineering practice.

Summary
The increasing interest in cross-laminated timber (CLT) construction has resulted in multiple international research projects and publications covering the manufacturing and performance of CLT. Multiple regions and countries have adopted provisions for CLT into their engineering design standards and building regulations. Designing and building CLT structures, also in earthquake-prone regions is no longer a domain for early adopters, but is becoming a part of regular timber engineering practice. The increasing interest in CLT construction has resulted in multiple regions and countries adopting provisions for CLT into their engineering design standards. However, given the economic and legal differences between each region, some fundamental issues are treated differently, particularly with respect to seismic design. This article reflects the state-of-the-art on seismic design of CLT buildings including both, the global perspective and regional differences comparing the seismic design practice in Europe, Canada, the United States, New Zealand, Japan, China, and Chile.
